firomatic fusible safety valve supplier

Recently, we became aware of a design deficiency in our ½” ‘Firomatic’ Fusible Safety Valve part number 12130. This bulletin covers ONLY the ½” FPT version p/n 12130, previous  p/n B200F.

Under certain conditions, if the valve is exposed to temperatures exceeding the handle’s temperature rating and the valve ‘fires’ or actuates, the stem may not travel far enough to properly seat the valve and shut off the flow of fuel. This could result in a dangerous situation if there is a ruptured fuel line downstream of the valve. There have been no reports of this situation arising, but the potential for this issue to occur does exist. This does not affect the valve’s operation when used as a manual shut off valve.

The current design of the 12130 – ½” FPT valve and handle assembly was in production prior to R W Beckett’s acquisition of the Firomatic® product line. We have been unable to determine exact dates for any changes made to the design by previous manufacturers. Therefore this bulletin covers all Firomatic® ½” FPT valves, whether using our part number 12130 or the obsolete part number B200F, used by Highfield Manufacturing. Suspect valves can be identified by the name ‘Firomatic’ cast into the body of the valve. See illustration below.

A re-design of the 12130 valve will be available pending agency approvals and manufacturing process lead times. We are anticipating the re-designed valve to be available by January 1, 2017.

Please immediately begin identifying suspect valves in service for retrofit. Retrofit kit part number 12130VR will be available from any Beckett Distributor or by contacting our Customer Service Department. A $50.00 Labor Allowance will be paid for each valve retrofitted. Instructions for adding the kit to installed valves are included with the kit. Estimated completion time to perform retrofit is less than 10 minutes.

To retrofit an existing valve, approximately 3½” of clearance above the top of the valve stem will be required. If there is not enough clearance to proceed with the retrofit, the valve will have to be replaced or an additional valve will need to be installed downstream. Availability of replacement valves is pending (see above). Along with credit for the valve, a $125.00 Labor Allowance will be paid for each valve replaced.

Only ‘Firomatic’ versions of this valve are affected. A picture of the affected valve is shown above. ONLY those valves with the name cast into the valve body need attention.

Guide to OSVs - Oil Line Safety Valves: this article describes check valves and fusible link oil safety valves used on oil piping at heating appliances as both a fire safety device and to assist in oil burner servicing.

We explain the purpose of OSVs, which way to turn the OSV or oil line safety valve to open or close it, and we describe common oil line valve installation or use mistakes.

How & Where do We Install a Fusible-Link Firomatic™ Type Oil Safety Valve? This article series explains the installation & use of OSBs, or Fusible Link Oil Safety Valves. We describe and explain the differences in function and use among fusible link fire safety valves (OSVs) like the Firomatic®, vacuum operated OSVs like the Webster OSV and Suntec PRVs, oil line check valves, Tiger Loop and other oil system air removing devices, and oil delay valves or quick-stop valves that are also referred to as oil safety valves.

We explain where each valve is installed and what it does. We include oil safety valve and check valve troubleshooting advice, and we describe defects in heating oil piping & control valves.

The OSV or oil safety valve controls flow of fuel oil to the oil burner of oil-fired heating boilers, furnaces, and water heaters. This inline oil valve is intended to close automatically and thus stop the flow of oil in the oil line in the event of a fire.

Some suppliers use other names for this valve including the "Firomatic" valve (R.W. Beckett) or the "Oil Safety Valve OSVA-38" (Capital City Tool, Inc.).

Fusible Fire Safety Valves are designed to reduce fire damage by shutting off the flow of oil from the oil tank in the event of a fire. These valves conform to UL/ULC 842 and are listed in the US and Canada. They are required by code in residential oil heating installations in conformance with NFPA 31. - R.W. Beckett [4a]

Because the valve includes a fusible link (a lead or other soft metal core), in event of a fire the fusible link melts and the internal spring pushes the valve stem down, closing the valve and stopping oil flow.

Sometimes additional stop valves or OSVs may be installed at other locations (such as at the outlet of an above ground oil storage tank), but the critical location is at the oil burner since that"s a more likely location at which a fire may occur.

Watch out: the Firematic™ fusible-link automatic oil line shutoff valve (photo at left) should only be present on the oil supply line. We explain below

that installing an OSV on the return line of a two pipe oil system can lead to disaster. Instead, where it is necessary to prevent leakage from the return oil line during oil burner servicing we can install a simple one-way check valve on the oil return line (if the oil burner"s fuel unit manufacturer permits.)

Our photo at below left shows an example of a Firematic™ safety valve right at the oil burner. Synonyms people use for this valve include OSV, fire safety valve, oil line valve, Fire-o-Matic valve, Fusible link valve, oil line shutoff valve, oil safety valve, and Fireomatic valve.

In particular, the OSV shown here is installed between the oil filter canister and the fuel unit intake port. That means that it would be impossible to service the oil filter without spilling heating oil unless the service technician finds another oil line shutoff valve somewhere between the oil tank and the inlet side of the oil filter.

With the shutoff valve between the filter canister and the oil burner (above right), changing the oil filter in the canister will require the service tech to go to the more distant oil tank to find and close a valve in that location (if one is even present).

The technician moved the Fire-o-matic OSV to its proper location at the inlet side of the oil filter, and he also installed a Firomatic oil line check valve between the oil filter and the oil burner.

This is an important fire-safety detail as in event of a fire a closed valve on the return line (if it closes before the OSV on the supply line) could cause blowing seals on the oil pump or a blown oil line fitting, spewing fuel oil over the building fire.

In sum, the proper place for the fusible link oil valve (Fire-o-Matic Safety Valve™ for example) is on the oil supply line just before the inlet to the oil filter canister (red arrow, below left), not between the canister and the oil burner as shown at below right (orange arrow).

Regarding "the best location of an oil filter", NFPA 31 (2011): 7.5.8, for indoor tanks up to 330 gallons, requires that a thermally activated shutoff valve be placed inline as close as practical to the outlet from a tank and that a proper filter or screen be installed downstream and WITHIN SIX INCHES of the required thermally actuated valve. If it"s required in the code, it doesn"t have to "the best" - it just has to comply with the code.

Many oil heat technicians sensibly want to install a fusible-link oil supply line valve at the oil burner, not only because this makes servicing the oil burner easier but because it also recognizes that the most-likely location of a fire is at the oil burner rather than possibly at a more distant oil storage tank.

The photograph above shows the right location for this safety device: at the input end of the oil filter. This permits the service technician to conveniently turn off the oil supply inorder to change the oil filter cartridge.

The writers of NFPA 31 (2011) 7.5.8 as specified above were focused on safety including wanting to avoid oil spills from the tank, but they might also have recognizede that putting an oil filter at the oil tank protects the oil line (between tank and oil burner) from sludge-clogging.

In our OSV photos below, the first photo (below left) shows the oil line safety valve in the OPEN position - oil will flow when the threaded portion of the valve shaft extends fully up through the rotatable knob pointed to by my pencil.[Click any image to see an enlarged version. Thanks to reader Bernie Daraz for pointing out the need for these two photos]

In our heating oil line valve photo at above right the valve has been manually CLOSED - no oil will flow. The threaded valve stem has disappeared down into the valve body and has shut off the valve and oil flow.

Watch out: if (for example in case of a fire) the fusible link inside of an OSV has melted permitting the spring to close the valve, then from outside the valve may look as if it is in the open position - the threaded stem will still be poking out - but the valve has snapped and closed internally. Most likely you"ll know this also because there will have been a fire or other horrible event that melted the OSV fusible link.

Watch out: A simple oil line shutoff valve may not be a fusible-link safety valve. The simple shutoff valve might be any plumbing valve that can manually stop oil flow in the line, but it is not a safety device.

Make sure you"ve installed a fusible-link safety valve at each location where it"s most needed - at each oil burner. Even when one of these valves is installed at the oil tank the proper place for this protection is on the fuel oil supply line

In the event of a fire, if the return oil line valve closes before the supply line oil valve your oil burner pump may burst the oil line or it may cause a fuel pump gasket or seal to fail, leading to uncontrolled oil flow and perhaps worse, spray heating oil everywhere, possibly feeding the building fire.

Thanks to Dave Ferris for this fire safety tip and thanks to reader Rick Johnston for adding clarification. (Note that not oil burners use both an oil supply and oil return line between the oil tank and oil burner.)

Watch Out: If the oil line fire safety valves are missing or are not at the right location, we recommend immediate installation of a Fire-o-matic™ type oil line safety

Recommended (red arrow, photo above left): an automatic oil line shutoff valve on the oil supply line right at each and every individualoil burner: (a type that will shut off oil supply to the heating equipment in the event of a fire, such as a Fire-o-Matic™ valve) is shown in our photo at left.

By every oil burner, we mean for example that if your heating system and also your hot water heater each has its own oil burner then each burner should have an oil safety valve. (As in our photo above left).

A common but poor practice is to install an oil valve just at the oil tank or perhaps installing a single oil safety valve at the oil burner for the heating boiler but omitting the oil safety valve for the oil fired water heater in the same building.

A second oil line shutoff valve on the oil supply line at the oil tank (photo above right) is ok as long as you have also provided the first oil safety valve at the oil burner(s).

Some service technicians install a second oil safety valve at the oil tank or at another remote location away from the oil burner, such as at the building wall where an outdoor oil tank line enters the building, or right at the oil tank (photo at above right - this oil tank valve is leaking).

This second valve is helpful if it becomes necessary to replace the oil line between oil tank and oil burner. Although our photo above shows a fusible link oil valve at the oil tank, the oil line shutoff valve at the oil tank or at a location remote from the oil burner or other more likely fire sources can be a normal plumbing stop valve.

However a common exception we see in the field is an OSV at the oil burner and a second OSV (or perhaps a simple shutoff valve, not thermally linked) at the oil tank end of the oil line.

Use an oil line check valve instead. Or if the heating equipment manufacturer recommends against using a check valve in the oil piping system (Suntec prohibits, Webster recommends) then leave it out.

Our photo (left, red arrow) illustrates this hazard: you will see fusible link safety valves on both the oil feeder line (blue arrow, left side of photo before the oil filter canister) and the oil return line (red arrow, right side of the photograph).

Unlike a fusible link OSV that shuts in response to high temperature to provide fire protection at the oil burner, a vacuum operated OSV opens only in response to a "sustained vacuum" created at its outlet end when the oil burner"s fuel unit pump is drawing oil from the supply.

Vacuum-operated safety valves offer protection against oil line leaks and against overpressure conditions on the supply side of the fuel unit. They are not a fire-safety valve.

If two oil lines are used to supply an oil burner, (a supply and a return) install an oil safety valve or OSV or fusible link oil line shutoff valve only on the oil supply line at the oil pump on the oil burner.Do NOT install an automatic oil line shutoff on the return oil line between the oil burner and the oil tank.

If a protection against oil back-flow at the return line is a concern, and if the manufacturer recommends it, use a check valve instead. Check valves like this one permit oil to flow just in one direction. They do not close down in event of a fire. Installed on the oil return line a check valve permits oil to flow from the oil pump in one direction only: back to the oil tank.

The Firomatic® oil line valve can be installed in ANY position - (vertical, horizontal, upside down) at least that"s what we were taught and what we have seen - the valve is spring loaded.

In a fire the fusible link, a lead core, melts at 165°F and a spring in the valve assembly snaps the valve shut to assure that the heating system does not feed oil to a building fire. It has to work in any orientation.

This list provides some of the companies produce fusible-link inline oil safety valves (OSVs). The footnote links point to the companies" contact information in our REFERENCES section, but generally you would purchase an OSV from your local heating equipment supplier or plumbing supplier.

RW BECKETT RECALL for FIROMATIC 1/2" FEMALE PIPE THREAD FUSIBVLE SAFETY VALVE [PDF] P/N 12130 - the stem may not travel far enough to shut off the flow of fuel if exposed to trip point temperature.

It might matter tremendously which way your OSV or oil safety valve is installed and in any event we ought to follow the manufacturer"s instructions including the flow arrow.

Those Webster OSVs include an internal valve that is designed to OPEN in RESPONSE to the FUEL UNIT OPERATION. So if the valve is installed backwards that feature will not work and the fuel unit may not pump oil properly to the burner nozzle.

Fusible Fire Safety Valves are designed to reduce fire damage by shutting off the flow of oil from the oil tank in the event of a fire. These valves conform to UL/ULC 842 and are listed in the US and Canada. They are required by code in residential oil heating installations in conformance with NFPA 31.

All valves are embossed with the direction of oil flow and include unique part number identification ring or each valve. The seal stem uses a double seal washer/ o-ring system with high grade Viton® equivalent materials suitable for No. 2 fuel oil, Kerosene and up to 20% Biodiesel blend.

Watch out: That"s because in the event of a fire a lead core in the valve is intended to melt to allow the valve to close - to stop feeding oil to a possible building fire. So if the valve is jammed it"s unsafe.

My concern is the stem does not go back into the valve or come out of it any further than it currently is no matter which direction I turn the valve or how many turns I make. Since the valve does not STOP turning in either direction, I"m concerned the valve is faulty.

If the stem pokes up out of the valve handle you"ve screwed the valve "down" and it is "open" to pass oil. Remember that these valves are threaded opposite of most others.

The knob on my OSV does not tighten up no matter how many times I turn it in either direction. The threaded stem in the center is protruding out about 2mm so I"m not sure if the valve is fully opened or closed. Is there a fix for this or do I need to replace the OSV?

If you have a fusible link valve that doesn"t seem to turn off you might try tapping the exposed end of the valve stem. I have found a stuck, or slow to close OSV on a few rare occasions. A gentle tap, not hard enough to damage threads, loosens it after which I open and close the valve a few times to convince myself it now moves freely. A burr on the brass interior or more likely internal sludge or debris could be the culprit.

Because at the oil burner the OSV is likely to be used at least once a year during service, that"s a good opportunity to discover if the valve is not closing fully.

In my opinion painting a fusible link is potentially unsafe - paint may interfere with mechanical operation of the valve. Most likely the manufacturer will agree, though they may not have imagined that event.

there must be an exception to the rule. my firematic valves open counter-clockwise and close clockwise and are definitely firematic valves because of their construction. they are just like the photos above but turn in the opposite direction you describe

Also, how do you recommend trouble shooting this? There are several valve one at each end of the supply line and one before the tigerloop that I could close for a few hours and see if it solves the problem (that would atleast narrow it down to a few fittings)

On a manual 1" fireomatic valve where the bonnett section joins the valve body, is that a brass on brass fit or is there suppose to be an o-ring or gasket? Does the OEM (Fireomatic) permitt valve disassembly for installation purposes? Thanks.

Mike I"ve installed these valves but have not tried disassembling one. If your unit is from Beckett, who currently provides the Fireomatic oil safety valve as well as the "New England Safety Switch" that uses a similar mechanism, then you might give them a call to ask.

Is there a inspection protocol for these valves like Morrison has on there fusible link valves (some quarterly inspections some yearly) and are they fine to use on gasoline lines I see only oil mentioned.

Watch out: do not use an oil line safety valve in ANY application other than those listed by UL and by the manufacturer - in this case, on heating oil supply lines.
