gas safety valve thermocouple manufacturer
Gas Safety ValvesThese valves automatically control main gas flow. Our automatic pilot valves shut off both the main and pilot gases. Pilot gas is tapped from the main line within the control. Gas will flow only to the pilot burner when the reset button is depressed. The manual pilot valve stop can be adjusted for maximum pilot flow.

Whether you are designing a regulation system for irrigation or merely looking for a new replacement, you will be able to find whatever type of thermocouple gas safety valve that you need. Our products vary from check valves to pressure reducing valves, ball valves, butterfly valves, thermostatic mixing valves, and a lot more.
Flame safety is a critical aspect of any gas-fired system, but it can present puzzling choices. What equipment do you need? Which parts can be substituted? At Charles A. Hones, Inc. we use Johnson Control’ line of Baso™ safety valves and other components to tailor flame safety on Buzzer gas burners and furnaces to the user’s needs. This brief guide can help you select the right equipment for your job.
The H15 series Baso valve will provide 100% shut down of gas flow in the event of pilot failure. The H15 series valve is recommended for low pressure gas only (1/2 PSI or 14”w/c). We supply this valve in four types of sets, as follows.
Note: Many Buzzer furnaces already include a #50 cast iron pilot (including the 171A, #250, #2700, ACR 60, and 185 salt bath furnace). Many Buzzer furnaces also come equipped with a redundant pilot system in which the smaller J99 style pilot ignites off the larger #50 cast iron pilot. Please call the factory if you have any questions. Additionally, parts can be substituted. For example, for an IH300 straight style complete with solenoid valves, gas cocks, and pressure gauges, you will need to replace the 60” thermocouple with a 72” thermocouple. This would add $16.00 to the cost. Please refer to the parts price list or call the Hones factory to assist in such modifications.

These valves do not fail very often. Normally the problem is with the ignitor not drawing enough amperage to open the valve. Even if the ignitor is glowing orange it is likely still the cause of the burner not igniting. Technicians refer to this as a "weak" igniter.

We have high quality Robert-Shaw thermostat gas controls which are ideal for smokers, smokehouses, deep fryers, hog roasters, pig cookers, and many other set-temperature control range applications.These thermostat gas control units are all-in-one assemblies which do not require electricity to operate. They have a built-in safety so that if the pilot light extinguishes, the gas to both the pilot and the burner(s) will be shut off within 20-30 seconds. Thermostat gas control unitscome with thermocouple, pilot light with tubing, piezo spark-ignitor to light the pilot, a temperature probe, and a 3/8” ID outlet gas hose. These pieces are all 5"-6’ in length. Thermostat gas control units will turn the burner on and off based upon the set temperature control range. Theycan be used with low pressure propane or natural gas; maximum inlet pressure is 0.5 psi.
The present invention relates to a thermocouple safety device, particularly for gas burners, according to the preamble to main Claim 1. Technological background
Thermocouple devices of the type indicated are used widely for controlling the flow of gas in burners of domestic heating boilers, of cooking hobs, of gas ovens in general, and all similar apparatus. Apparatus of this type generally has a gas-supply valve the opening/closure of which is controlled by an electromagnetic unit which is connected to a thermocouple for ensuring safety shutting-off of the valve if the flame in the burner should accidentally go out. Typically, the potential difference generated by the thermocouple as a result of contact with the flame serves to keep the closure member of the valve in the open position by electromagnetic attraction and in opposition to a biasing force, generally of a resilient nature, for ensuring the safety closure of the closure member in the absence of a flame.
It is known to mount the contact terminals of the thermocouple, which are normally constituted by a phase conductor and an earth conductor, on a body of the valve unit, by connection with threaded connectors. This system has been found particularly inconvenient since it requires the use of tools for mounting/removal operations; moreover, it may be unreliable owing to possible slackening of the threaded connections.
It is also known to mount the contact terminals by means of quick push-fit connectors both for the phase conductor and for the earth conductor. An example of a device having these characteristics is known from European patent No. 619460. This describes the mounting of the thermocouple by the provision of a pair of axial push-fit connector elements on the body of the valve unit and a corresponding pair of push-fit connector elements on the thermocouple terminals for making a connection by the quick axial push-fit connection of the phase and earth conductors to the valve body. Description of the invention
A principal object of the invention is to improve the tightness of the connection between the terminal and the valve unit, in particular insuring improved axial
locking of the thermocouple terminals relative to the valve unit with respect to possible slipping-off of the conductors, but at the same time to ensure that operations to mount and remove the thermocouple are very quick.
This and other objects which will become clear from the following description are achieved by the invention by means of a thermocouple safety device formed in accordance with the appended claims.
With reference to the drawings mentioned, a safety device according to the invention, with a thermocouple 2, for a gas burner (not shown), is generally indicated 1.
The thermocouple 2 of the device comprises a phase conductor 3 and an earth conductor 4 each carrying, at a corresponding end, a respective terminal 3a,
The electromagnetic unit 5 is housed in a tubular body 6 of the device in which a gas-supply valve seat (not shown) is formed in conventional manner; the valve seat is associated with a respective closure member, also not shown, the opening/closure of which are controlled by the magnet of the unit 5 in a conventional manner which is not a subject of the present invention.
The clip-like connection element 11 and the collar-like element 7 are advantageously made of electrically-conductive material so as to ensure the electrical connection of the earth conductor 4 to the electromagnetic unit 5. In order to improve the axial locking of the thermocouple 2 relative to the body 6 of the device, auxiliary axial restraint means are also additionally and optionally provided. These means comprise a projection 15 produced by the right-angle bending of an end of the plate-shaped region 14 of the clip, which can engage a circumferential groove 16 defined in the collar 7 when the clip 11 is snap-fitted on the collar. The groove 16 is preferably defined by opposed and facing shoulder surfaces 17, 18 extending from the collar-like element 7 and from the tubular body 6, respectively. The projection 15 has a circular recess 15a suitable for mating with the cylindrical surface of the base of the groove 16, for improved mutual bearing contact.
In operation, the mounting of the thermocouple involves, initially, the connection of the phase conductor 3 by the axial quick push-fit connection of the connectors 9, 10 and, subsequently, snap-fitting of the clip 11 by movement perpendicular to the axial direction in the direction of the arrow F of
Figure 1; this fitting ensures the axial restraint of both of the terminals of the conductors 3, 4 of the thermocouple relative to the tubular body 6 as well as ensuring the electrical connection of the earth conductor 4.
Conversely, to disconnect the thermocouple 2, it is necessary to remove the resilient clip 11 from the collar-like element 7 preliminarily (so as to disengage the earth conductor 4) and then to disengage the quick push-fit connection of the phase wire 3 axially.
Amongst these should be included improved axial locking of the thermocouple which is brought about independently of the quick push-fit connection of the phase wire. One of the main advantages is that quick and easy connection of the thermocouple is ensured with a limited overall transverse dimension of the device.
1. The FMDA safety valve is the only type with the thermocouple permanently attached to it. This means the thermocouple cannot be replaced; the entire safety valve must be replaced if the thermocouple fails. The easiest way to identify an FMDA type safety is a ½” diameter red button on the bottom of the valve. You must know the gas pipe size and if the pilot tube is an “in and out” or an “out only.” An “in and out” safety valve has two threaded holes at the top of the part, one for gas for the pilot to come in and one for gas to go out. An “out only” safety valve has just one threaded hole to connect gas for the pilot to.
2. The BASO safety valve can vary in design depending on the piece of equipment it is on, so it is important to know the brand name, model and serial number of the piece of equipment to get the correct safety valve the first time. The easiest way to identify a BASO valve is by the 15/16” diameter red pilot button. The thermocouple is separate from the safety.
3. The TS type safety valve is the only one that can be rebuilt. It is similar to the FMDA and BASO types in that it has “in and out” or “out only” pilot tubing, so you must know what is in your equipment. A rebuilt kit is available in both and it is not necessary to replace the body unless it is damaged. The body has no moving parts in it. The easiest way to identify the TS safety is by the 5/8” diameter red button. The thermocouple is also separate from this safety, similar to the BASO.
If the wire leads are screwed to the top terminal block, and two tubes are coming out of the top of the valve, it is the tubing type combination safety valve.
