Changing an LPG (Liquid Petroleum Gas, otherwise known as Propane) cylinder can injure a forklift operator if the seal in the cylinder valve has failed, as a defective seal can allow the liquid propane gas to spray over the hand or face of the operator. Since liquid propane vaporizes quickly (-44° F or -42° C), it will cause extreme frostbite when in contact with the skin. The solution is to place this shut-off valve on the hose, preventing the liquid propane from coming back onto the operator. When closed, the valve shuts off LP Gas to the coupler preventing gas from coming back through the hose if the seal fails. This is important, as most LPG forklift cylinders are rented and the operator does not know the condition of the seal or age of the cylinder without rigorous inspection. When the valve is open, the high-visibility shut-off handle covers the coupler so that the valve cannot be disconnected. Quick and easy installation.

Changing a LPG cylinder on a forklift can sometimes give a forklift operator a big surprise!  The seal in the cylinder valve can fail causing liquid propane gas to spray over the hand or face faster than they can react.  Liquid propane vaporizes quickly (-42 degrees C or -44 degrees F) and will cause extreme frostbite if it contacts the skin.

The Solution: Placing a shut-off valve on the hose with the Propane Coupler to prevent the LPG from escaping back on to the forklift operator and escaping in to the surrounding environment.

Once the propane coupler has been installed and the lever is then opened the lever handle will prevent anyone from removing the Propane coupler.  The lever must be closed before the propane coupler can be loosened off.

The reason why cylindrical tanks for LPG (liquid propane gas) fuel systems for vehicles are so widespread is that, for many years now they have been the only type of fuel tank of this kind available. These cylindrical tanks feature the valve group ring located right in the middle of the tank or on the side of the cylindrical ferrule. The tank is generally located in the trunk against the rear seat back or in the space between the two rear wheels. The fact that the valve group and, even worse, the airtight chamber, are placed right in the middle creates an additional impediment, besides the tank itself, with the obvious reduction of the trunk"s loading capacity and seeing that the airtight chamber often has projecting parts of its own this also entails the risk of damaging any luggage or packages one puts inside the trunk. Furthermore, in order to access the valve group, in case of need, it is necessary to empty the trunk of all its contents, given the position of the valve group right in the middle of the tank.

According to the present invention there is provided a cylindrical liquid propane gas tank with a cavity located on either one of the two ends capable of housing the valve group ring, or the rings for the single valves, in the case of the embodiment designed for the foreign market, which is shaped so as to fit perfectly inside the cavity. In this manner, the front of the cylindrical tank described herein will be totally free of any protruding parts, thus enabling a better exploitation of the trunk space. Furthermore, the recessed position of the valve grouping or valve rings and of the airtight chamber also allows the easy and safe passage of the pipes to the outside, exiting through a hole in the section above the wing. The recessed cavity housing the valve group is closed by an airtight cap that may be opened if the need arises to inspect the valve group or valves.

As described above, the cavity for housing the valve group or valves may be applied to one of the two ends of the tank in such a manner that the valve group, or valves in the case of tanks designed for the foreign market, are perfectly recessed. Obviously, such a cavity may also be located on the bottom of the front of the tank, at different angles, in which case the valve group or valves shall still be recessed and there will be no projecting parts. One of the alternative embodiments shall be provided with a transparent polycarbonate cover with holes provided with adequate seals through which pass the knobs for opening and closing the valve group, which knobs may be easily used to open or close the gas flow without opening the cover.

Referring to the drawings, and in particular to FIG. 1, the end 1 of the tank 2 is provided with a cavity 3 housing the ring 4, or the rings in the case of the tank designed for the foreign market, for the valve group or valves 5. Said valve group ring or rings is/are shaped in such a manner as to fit perfectly inside the cavity.

The cavity will preferably have walls 6 and 7 placed at right angles and is located at the curved end 1 of the tank 2 so that even after the valve group 5 has been installed it is perfectly flush-mounted with the surface of end 1 of the tank 2.

The pipes 8 exit from the valve group and wheelhouse 11 through the passage 9, shaped like the mouthpiece of a flute, and made suitably airtight by means of silicone or any similar substance 10. An airtight cap 12, hinged at 13 so that may be opened for inspection purposes and shaped so as to be flush-mounted with the cylinder end, closes the valve group 5, or the valves, in the case of the embodiment designed for the foreign market, thus forming an airtight chamber.

FIGS. 2 and 3 show how the cavity housing the valve group is positioned with regard to the tank diameter, in this case also the airtight cap 12 is shaped so as to be flush-mounted with the tank.

FIG. 8 shows a projection of the tank with the cavity housing the valve group ring 4 and it is clear that the valve group ring and the valve group itself no longer project outside the tank, thus taking up practically no space at all.

FIGS. 9 and 11 show a further embodiment where the cavity housing the valve group ring and the valve group, or valve rings and valves, is located at the side of the cylindrical tank, in the same position in which the valve group 5 or the valves are usually placed. In this case, the cavity 3 has a regular shape and the two pipes 8, one for filling the tank and the other for fuel supply, run alongside of the tank (see FIGS. 10 and 11) and exit from the two passages 9 shaped like the mouthpiece of a flute. In this case also the cavity housing the valve group or valve is sealed by an airtight cap that may be opened for inspection purposes. The recessed position of the valve group 5 does away with all projecting parts, which, on the contrary, are generally present on traditional tanks.

The embodiment shown in FIGS. 12 to 17 has the valve group 14 housed in the specific housing 16 of the LPG tank 15. The housing 16 is closed by a polycarbonate cover 17 shaped exactly like the tank, so as to follow its contour, and provided with holes 18 out of which pass the supply and airtight chamber ventilation pipes; of holes and housings 19, 20 and 21 for the screws or other similar means for fastening the cover 17 to the valve group housing 14. In the middle of the cover 17, in an easily accessed position, there are two holes for the knobs 22 and 23 to be used for opening or closing the gas flow.

As may be seen in FIG. 17, the cover closing the valve group housing is also provided with a specific seal 25 preventing any gas leaks and the holes 19, 20 and 21 for fastening the transparent cover, made of polycarbonate or other similar material, to the valve group housing are also provided with adequate seals. Obviously, if so required for maintenance purposes, the cover may be speedily and easily removed simply by removing the fastening means 19, 20 and 21.

The advantages of the tank described herein are obvious in particular, the following must be highlighted: improved exploitation of the trunk, easy access to the valve group, even if the trunk is full, and easy installation, due to the fact that the pipes 8 required for filling the tank and supplying fuel to the engine exit from the vehicle almost immediately, thus reducing the pipe sections inside the trunk and the necessary maintenance.

Houses or buildings utilizing gas energy require a gas piping system to power heaters, ovens, and other heating appliances. One of the most important elements of a gas piping system is the propane service valve, which controls propane gas flow in and out of a building. While there may be many other valves within gas plumbing, this valve functions as an on/off switch and serves as the main point of control for cutting off or allowing for the flow of gas into a piping system.

Propane valves are simply used to turn gas on or off. Similar to that of a water faucet, propane valves consist of a handwheel that controls propane gas flow when turned. When the wheel is turned, a stem and seat mechanism located within the valve opens or closes to prevent or allow gas flow from the tank.

Using propane gas requires an LP gas regulator, which decreases the amount of pressure released into the gas line, keeping it at an acceptable and safe level while still meeting the needs of the application.

There are multiple different valves in any propane system, each of which has a particular job. At IPS Equipment, we provide some of the most common types of valves for propane systems, including:

A pressure or safety relief valve is a safety mechanism that every propane system needs. It allows excess pressure in the tank to be slowly and safely released. Without this valve, pressure can build up and cause the tank to crack or rupture.

The relief valve has a pressurized spring. If the pressure levels within the tank grow too high, the spring forces the valve open just enough to return the pressure levels to acceptable levels. Once the pressure decreases, the spring relaxes, and the valve automatically closes.

This valve is where gas delivery personnel add new gas to a propane tank. Propane delivery trucks have hoses that can be attached to the filler valve so propane can be pumped into the tank. This valve is also pressure-activated, and it opens automatically in response to the pressure in the hose.

Filler valves have gaskets that operators can push the hose end against to avoid propane leaks. They also only allow for unidirectional fluid movement, meaning that once the tank is full, there is no risk of propane escaping when the hose is withdrawn.

This shut-off valve prevents gas from entering the building and any attached appliances. You can use this central point of control like an on/off switch to completely halt the path of gas in the system.

This valve is also called a vapor return valve or vapor eliminator valve. It ensures that propane is delivered at the proper pressure levels from the propane delivery truck to a personal tank and returns any excess propane back to the delivery truck. This is similar to a safety valve, except the vapor equalizing valve ensures the propane is delivered at proper pressures for optimum use, not safety. This is especially crucial during hot weather or in warm environments, as that can increase the pressure.

This specialized valve is meant for use by propane companies only. It allows operators with the proper tools to drain liquid propane from the tank. Propane tanks must be drained to <5% capacity levels before they can legally be moved.

When you choose propane forklifts, you have choices for refueling — both of which your propane supplier can help you navigate safely. You can choose a cylinder exchange program, where your propane supplier refills the cylinders for you. Or you can choose on-site refueling, where trained members of your team refill cylinders themselves.

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.
