We are happy to introduce our brand new line of low pressure gas solenoid valves from Atlantic Valves. The addition of these specialty valves will give our customers a reliable way to control the flow of gaseous media within their systems.
About Low Pressure Gas Solenoid Valves
When working with gasses like propane and natural gas, it is incredibly important to make sure there are no leaks in the system. Regular liquid/water solenoid valves will stop the flow of liquid and other media that naturally create a strong seal with the higher pressure differentials. Low pressure systems with gas won’t create enough pressure to form a complete seal, allowing gas to still flow through a shut valve.
Our new gas solenoid valves were designed specifically to tackle this problem.
How a Low Pressure Solenoid Gas Valve Works
These low pressure valves work similarly to a regular solenoid valve, but the design and parts are tweaked to accommodate the low pressure of gas as compared to a liquid running through your system.
How a 2-Way Solenoid Valve Works (for an overview of typical solenoid valve operations)
Two major changes were made to the gas valves to make a perfect “air-tight” seal that only allows gas to pass through when the valve is activated: a higher tension spring and NBR diaphragm
The higher tension spring is made of strong stainless steel that forces the seal into place and holds it indefinitely.
Unlike other solenoid valves that use a Viton® diaphragm, our new line of low-pressure solenoid valves utilizes NBR (Nitrile Butadiene Rubber) seals that are better equipped for gaseous media. Viton® is a rubber that has more chemical compatibility and is suitable for higher temperatures, but will become inflexible and hard as the temperature drops. NBR is a tear-resistant rubber that can withstand colder temperatures without degrading, thus keeping its original shape and properties under lower temperatures and forming an airtight seal.
Low Pressure Valve Applications/When is a Gas solenoid Valve Required?
As the name implies, these are made for low pressure applications, using gaseous media flowing in one direction.
These valves can be used with liquid media, but the flow rate would be lower than optimal for most systems. For that, we would recommend our ZW series solenoid valves or a full bore motorized ball valve.
The low pressure valves are ideal If you are looking for an automatic and/or remote solution to control the flow of natural gas, propane, or inert gasses.
