Low-Pressure Gas Valves
Low Pressure Gas Solenoid Valves
Low pressure solenoid valves are recommended for controlling the flow of gaseous media. These particular gas valves are better equipped to create an airtight seal within the valve to prevent leaks within the system and keep it running optimally.
Solenoid Gas Valve Construction
A gas solenoid valve is constructed similarly to other solenoid valves, except that they have a higher tension spring and use NBR (Nitrile Butadiene Rubber) seals rather than Viton® (Fluorocarbon rubber). This combination ensures that the valve seal stays in place under lower pressure and temperature conditions, preventing leaks within the gas system.
Low Pressure/Gas Valve FAQ
Why use NBR seals instead of Viton®?
Viton® seals are excellent for general applications, but are not reliable at lower temperatures commonly found in gas systems. NBR can withstand a temperature range of 15 to 250°F (-10 to 120°C) without fear of the material distorting, which would otherwise lead to possible leaks.
Are these Valves Compatible with My System?
Our Atlantic Valves solenoid gas valves are constructed with a brass valve body, NBR diaphragm, and stainless steel components. These are compatible with natural gas, propane, and inert gasses. Please see our chemical compatibility chart for more information on other media compatibility or feel free to contact us with any questions about your particular system.
Can a Gas Valve be Used with Other Media?
The short answer is, yes. However, these particular low-pressure valves are best suited for gaseous media. Liquid media can definitely flow through the valve, but with a much lower flow rate than you would expect from a standard solenoid valve or full-bore ball valve.
Are there Other Gas Valve Sizes or Metal Construction Options?
While we do have one of the largest selections of solenoid valves available, we may be out of stock in a particular option which would not show up on the site. If there is a particular type of gas solenoid valve that you need, please contact our offices or fill out our Special Order Request Form and our customer service representatives can help you find out when we are going to be back in stock or discuss special orders for valves we don’t currently carry.
