Gas Solenoid Valves are as versatile as they are useful. Translating electrical impulses, to open and close the valve, they control the flow of gas in a wide range of industrial and residential applications. In this tutorial article, PIF takes a closer look at what Gas Solenoid Valves do, what applications they're used for, and the key manufacturers of these handy types of solenoid valve.
With competitive price and timely delivery, ABYDA sincerely hope to be your supplier and partner.
Gas Solenoid Valves are made of parts that receive electrical impulses that then translate those impulses into mechanical movements. When an electrical impulse is received, by the Gas Solenoid Valve, it will open or close the valve. Thus controlling the flow of gas into a chamber or through a line.
A gas solenoid valve can be used in many applications. Both for commercial and residential devices. Commercial uses of Gas Solenoid Valves generally include any pneumatic machinery that uses gas pressure to move its parts. Manufacturing facilities might use solenoid valves to control the movement of gases used in their manufacturing processes.
Residential applications include solenoid valves used inside furnaces. These control when the gas comes on and is ignited by the pilot light to create warmth. Vehicles powered by natural gas use solenoid valves to control the flow of gas into the engines cylinders. While gas-powered clothes dryers also have solenoid valves to control the flow of gas into the dryer, which helps to prevent fires or gas poisoning.
ASCO provides the broadest line of solenoid & motorised shutoff valves designed to control the flow of fuel gas, liquid propane and all grades of fuel oil used in combustion applications such as: industrial furnaces, ovens, kilns, incinerators, burners and boilers. Solenoid operated valves handling combustion system pilot and main line fuel shutoff and control needs. These valves are available in 2-way normally closed, normally open, manual reset, and 3-way diversion.
Bürkert also produce solenoid valves for fluid and gaseous media , aggressive or neutral, applicable in various ranges of temperature and pressure. In fact, Christian Bürkert, founder of Bürkert is said to have pioneered the solenoid valve as we know it today, setting the international benchmark for industrial solenoid valves.
Buschjost (an IMI Norgren brand) manufactures a wide range of Solenoid Valves for use with different pressures, medias, temperatures and applications. The Buschjost range of Solenoid Valves include direct-acting solenoid valves, indirect-acting solenoid valves, or a combination of both; solenoid valves with forced lifting.
ASCO valves are available in brass, aluminium, and stainless steel. Their main features include junction box; pipe taps; visual indication; proof of closure; leading agency approvals; and pipe connections from 1/8 to 3. Most valves are rated for -40ºF service for outdoor installation in frigid climates.
Bürkerts range of gas solenoid valves are available in an extensive range of body and seal materials. From PTFE, to NBR, EPDM and even PEEK, this tutorial article on solenoid valve materials by Solenoid Valve expert Michael Hannig will tell you all you need to know.
This chemical resistance chart and solenoid valve selection guide from Bürkert is an extremely useful resource when specifying or choosing the correct solenoid valve for an application.

Finally, this technical tips video from Norgren Buschjost explain exactly how solenoid valves work in process applications, the different types of solenoid valves available and typical applications.
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.
Depending on the age of a tank, it may have an external pressure relief valve (found on older tanks) or an internal one (in newer models).
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.
