One thing you should pay attention to is the propane tank’s safety relief valve. All propane tanks, including the cylinders you use for your BBQ grill, are required by law to have pressure relief devices to allow for the release of excess pressure in the tank.

A spring keeps the safety relief valve closed as long as the pressure inside the tank is at a safe level. If the pressure in the tank reaches the same amount of pressure of the spring, the safety relief valve is opened. If that happens, you’ll hear a hissing sound coming from the tank. In instances where the pressure in the tank is much higher than that of the spring, the valve will fully open. You’ll hear pop if that occurs.

Your propane tank needs to have room for the propane inside it to expand. That is why your propane tank is filled to 80% of its capacity. The 20% of the tank that is empty space allows the propane to safely expand.

That expansion is why propane tanks are white or beige. Light colors reflect heat to minimize expansion. Dark colors retain heat and can cause the propane inside your tank to expand to dangerous levels. So, even if your propane tank doesn’t go with the color of your siding, leave it alone.

The safety relief valve is one of the most important and vital valves on any LP Gas container. All propane tanks and cylinders are required by law to be fitted with pressure relief devices designed to relieve excess pressure. The function of a safety relief valve is to keep a propane tank from rupturing in the unlikely event of excessive pressure buildup. Propane tank relief valves are also known as pop off valves, pressure venting valves or relief valves.

Relief valves are held in the closed position by the force of a powerful spring. As long as the pressure inside the tank is less than that of the spring, the valve will remain closed. If tank pressure rises to that of the spring, the valve will open resulting in a hissing sound outside the tank. If the pressure in the tank rises significantly higher than that of the spring, the valve will fully open. When the valve fully opens, it initially makes a loud pop followed by a blast of released propane gas. Once the pressure is released and the tank pressure falls below that of the spring, the valve closes.

Most propane tanks in residential and commercial service have internal safety relief valves. The reason for an internal valve as opposed to an external pressure relief valve is it presents less of an obstruction when moving the tank. Internal relief valves are generally placed near the end of the propane tank on above ground containers.

Found primarily on older tanks, external relief valves operate in the same manner as an internal relief valve with the spring mechanism being outside the propane tank itself. Relief valves on multvalves are always fitted with external safety relief valves. Older tanks with an external relief valve installed on the container are generally replaced with internal pressure relief valves, provided they are connected to a dedicated tank opening specifically designed for the placement of the relief valve.

Because the safety relief valve performs such a vital role in the protection of the propane tank, it should be maintained and repaired by licensed propane professionals only. Do not ever look into a relief valve or stand over it.

A protective cover should be placed over the relief valve to ensure proper operation. If the valve has debris in the upper mechanism of the relief valve and it opens, the debris may cause the valve to remain open resulting in a potentially dangerous situation and/or excessive loss of propane. A simple protective relief valve cover can be made from a plastic bag fastened around the external portion of the valve with a rubber band.

If a you encounter a relief valve that seems to be "hissing" (opened to relieve pressure) do not tap it or mess with it. If the tank has been recently filled in hot weather and the face gauge reads over 80 or 85%, spray some water from a hose on the tank. This may cool it down and reduce the expansion of the liquid in the tank. Call your propane company immediately and inform them of the situation.

Pictured here is a relief valve that was apparently leaking. Instead of calling the propane company to replace the valve, the customer decided to fix the problem himself. Using a soldering iron, he soldered the leak until it stopped leaking. In the process of "repairing" the leak, the customer completely sealed the relief valve in a closed position placing himself and his family in a very dangerous situation.

In this type of situation, a relief valve that is sealed shut will not allow the tank to vent excess pressure if it is overfilled or the pressure inside the tank exceeds the working pressure of the container. In a case where the tank is unable to vent to the outside, the tank is subject to rupturing causing more harm and damage than money saved by trying to fix it yourself. Let the propane company or LPG professional handle any problems with thesafety relief valve.

Propane tanks are popularly used in homes to provide fuel for dryers, cooking ranges, BBQ grills, dryers, and so much more. Propane fueled systems use pressure valvesto regulate the pressure of the gas when supplied from the tank to the appliance. To check damage and accidents, these devices are engineered to automatically adjust the pressure of the propane gas to a level that is safe for the appliance in use.

The valves primarily function with three main elements i.e., a restricting, loading, and a measuring component. Since propane tank valves are used in highly vulnerable environments, it is important that they are created from reliable and durable materials under thorough professional guidelines.

It’s summertime, folks, and that means it’s the grilling season. Sure, we all love grilling year round but there’s nothing quite like a summer barbecue. Before you fire up that grill I allow me to engage you in a quick discussion about our ‘propane bottles.’

Grilling cylinders are technically known as 20 lb. DOT cylinders because they are built to DOT specifications. DOT specifications include rules that deal with metal thickness, pressure capabilities, and longevity of the tank. These cylinders can only legally contain 20 lbs. of propane. Propane weighs 4.24 lbs. per gallon. That means there is approximately 4.7 gallons of propane in your grilling cylinder when it’s full.

Grilling cylinders can be refilled or exchanged at a cylinder exchange cage. Refilling stations must refill the cylinder by weight. That’s why when you get your grilling cylinder refilled, the attendant will place it on a set of scales before they start the pump. Sometimes the attendant even uses a screwdriver and opens a small hole in the valve. You’ll hear a hissing noise as the bottle fills. When the grilling cylinder reaches 80% capacity, a white mist will shoot out of the small hole indicating that the cylinder is full. ‘Full’ in the propane industry, when regarding tanks and cylinders, is actually 80% of the water capacity of the tank or cylinder being filled. Propane is very susceptible to temperature changes and will expand or contract greatly with changes in the outside temperatures. To compensate for this possible dangerous expansion, we never completely fill up a tank or cylinder. We always stop at the 80% level.

Grilling cylinders are equipped with all kinds of safety features. One such feature is the OPD valve. The OPD valve ensures that your grilling cylinder isn’t over filled. All cylinders that hold less than 100 lbs. of propane are required by law to have this type of valve installed. OPD stands for Overfill Protection Device and that is exactly what it is designed to do. As the cylinder is being filled and the liquid level rises, it also raises a small float attached to the bottom of the valve. As this float rises to approximately 809% of the volume of the tank, the valve will shut and stop propane from being allowed into the cylinder. Despite the OPD being required by law to be on your grilling cylinder, the law also says it must still be filled by weight. The OPD is a safety backup.

Many customers find that the cylinder exchange cages are the way that they prefer to get a full cylinder of propane for their grill. The customer brings an empty cylinder to the cage location, leaves the empty, and gets a full cylinder. The price for exchange is generally higher than having your cylinder refilled yourself but the exchange cage locations are generally open when a cylinder filing station may be closed. When using the exchange cages, the customer is assured that the cylinder has benen inspected and filled by a professional. Another drawback of the exchange process is that some companies will, by policy, not put a full 20 lbs. of propane in the exchange cylinder. Be sure to check the cage before purchasing to ensure that you are getting a full 20 lb. cylinder.

Another safety measure installed in grilling cylinders is an excess flow valve. The excess flow will engage and stop the full flow of propane through the valve if it sense that the gas line may have been broken or installed incorrectly. Over the years, I have seen customers open the valve swiftly, allowing gas to fill unpressurized gas hose so quickly that the excess flow ‘thinks’ that there is a problem and will shut the gas. It will release a small amount of gas to pressurize the hose on the downstream side of the valve in order to reset itself. For an unknowing customer, this small amount of gas being released is just enough to light a very small flame in their grill. This usually lends to the assumption that there’s something wrong with the grill. If this happens to you, simply turn off the burners on the grill and turn the cylinders valve to the off position and the excess flow will reset itself. You may even hear a small click when the reset occurs. After being reset, open the valve slowly (very slowly). Once the hose is pressurized, full gas flow will occur.

One last thing to be aware of when handling your grilling cylinder is a hissing sound coming from the back side of the valve. This is the pressure relief valve. It is designed to relive excess pressure that may build up inside of the cylinder. If you discover the valve is hissing or leaking, move the cylinder away from people and buildings in a cool place and away from any source of ignition. Call the person that filled the cylinder and follow their directions.

Beginning October 1, 1998, all newly manufactured small propane cylinders (capacity of 4 pounds up to 40 pounds) were required to be equipped with a over filling prevention device (OPD).

In most cases, consumers can tell if a propane tank has an OPD valve by the handles. If the handle is round or star-shaped (left) their cylinder is outdated. A triangular handle (right) indicates an updated cylinder.

There are limits on how much propane can be put into a cylinder. A properly filled cylinder will have a vapor space left in the top of the cylinder to allow room for expansion of the liquid with a change in atmospheric temperature.An overfilling prevention device is a secondary means of assuring that cylinders are not overfilled.

An overfilled cylinder doesn"t have enough space left if the liquid expands when exposed to warmer temperatures. This can cause an increase in cylinder pressure and create potentially hazardous conditions, such as:The pressure relief valve may open, discharging propane from the cylinder.

During the refilling process, a valve inside the cylinder closes when the proper level of propane is reached. Since the OPD currently in use measures the volume of propane in the cylinder, the weight of the propane will vary depending on its temperature. Check the posted information where you purchase propane to determine the net weight of propane in your cylinder.

Yes, an OPD must be installed on your old cylinder. If your cylinder is inspected for requalification before April 1, 2002, an OPD-equipped valve will be installed at that time. (All DOT cylinders require periodic requalification to ensure that they are safe for continued use.) Even if your cylinder is not inspected for requalification before April 1, 2002, it must still have an OPD-equipped valve installed on it by that date.

There are at least two ways to identify OPD equipped cylinders. New cylinder wrappers and/or warning labels will include this information. Second, most cylinders with OPDs have special triangular handwheels with the letters "OPD." (However, some OPDs were produced before the letters on the valve handles and valve bodies were required so check the wrapper or label or ask your propane refiller to identify the type of valve on your cylinder.)

The only reliable way to tell if your propane grill tank is full or empty is to weigh it. An empty 20lb propane grill tank will weigh around 18-20 lbs. A full propane grill tank will weigh somewhere between 38-40 lbs. The biggest problem with weighing a propane grill tank is that you must disconnect it from the propane grill. Most grillers never check their tank until they run out. The best way to ensure you never run out of propane is to always have a full spare propane grill tank!

The lifetime of a propane grill tank can vary. A 20lb cylinder can last indefinitely, as long as it is kept in good condition. The federal government requires that a new cylinder be inspected after 12 years of service, and every 5 years thereafter. The inspection is visual and includes checking for leaks and excessive rust/corrosion. After inspection, a new date is stamped on the propane tank collar to verify that particular tank is cleared for 5 additional years.

Occasionally, a propane grill will produce only a small flame or no flame at all when the tank is full and turned on. Many times, this is caused by the operator opening the valve too quickly. All OPD valves are equipped with an excess flow control in case of a hose breakage. To correct this problem, close the valve handle and turn off all burners on the propane grill. After waiting at least 15 seconds, slowly open the valve handle, being careful not to let too much propane gas flow at once. This process should keep the valve from closing due to a sudden excess flow of propane gas.

The "Pop-Action" design permits the RegO Pressure Relief Valve to open slightly to relieve moderately excessive pressure in the container. When pressure increases beyond a predetermined point, the valve is designed to "pop" open to its full discharge capacity, reducing excess pressure quickly. This is a distinct advantage over ordinary valves which open gradually over their entire range, allowing excessive pressure to develop before the relief valve is fully open. All RegO internal, semi-internal, and external relief valves incorporate this "Pop-Action" design.

Designed especially for liquid filling and vapor equalization of LP-Gas and anhydrous ammonia. The limited travel of the handle on the tailpiece minimizes spin-off, encouraging cautious removal to properly bleed off trapped product to ensure closure of the filler valve and hose end valve. The ACME threads are machined on a rugged steel insert which is permanently cast in the aluminum handle, providing for durability under repeated use.

These brass connectors are especially designed to join the carburetor fuel line to the service valve on lift truck cylinders. Sturdy, long lasting ACME threads allow quick, hand-tight assembly that provides for quick and simple cylinder replacement. Back checks automatically close in each connector when disconnected.

These brass connectors are especially designed to join the carburetor vapor fuel line to the service valve on industrial cylinders especially designed for and used on propane fueled lawn mowers. Sturdy long lasting ACME left hand threads provides for quick hand tight assembly that provides for quick and simple cylinder replacement.

Specifically designed to withstand the everyday abuse given to hose end valves on delivery trucks and hose end couplings on risers in bulk plants, these rugged plugs protect the coupling tip as well as prevent the entrance of dirt, dust, snow and rain. They also prevent possible gas contamination from these same sources. The heavily ribbed outer surface permits hand-tight make-up.

Designed especially to provide pull-away protection for LP-Gas and anhydrous ammonia transfer operations including transport and delivery truck loading and unloading, engine fuel container filling and miscellaneous cylinder filling operations. When properly fastened to the inlet end of the discharge hose, the valve is designed to stop gas escape from both upstream and downstream lines in the event of a pull-away. An excessive tension pull causes the valve to automatically separate, closing two internal back pressure checks. Only a few cubic centimeters of gas escape at the instant of separation.
