09/28 · Higher pressure on the outlet causes the valve to close. A check valve, also known as a non-return or one-way valve, is a two-port safety device that allows gas, steam, or fluid to flow in a single direction. Its primary purpose is to restrict backflow in a system. There are a variety of check valve stopping mechanisms, including a disc, piston

Jacksonville, Florida (September 16, ) Natural gas systems are designed to follow strict codes requiring secondary protection features to prevent over-pressurization. These systems are designed to eliminate single point of failure modes, however, systemic failure can even cause these redundant systems to fail under the most extreme conditions.

Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 3,000 psi. High-Temperature Threaded Check Valves.

Ball check valve. Video Credit: iecSimulations / CC BY 3.0. Advantages: Can be used with steam, air, gas, water, and vapor lines with high flow velocities, can be installed in lines with vertical flow, available with renewable seat rings. A double-disc or wafer check valve consists of two half-circle disks hinged together. The two disks fold together upon positive flow and retract to a full

What does the fuel overflow valve do? The overflow valve (a check valve) is used to route excess fuel through the fuel return line and back to the fuel tank. Approximately 70% of supplied fuel is returned to the fuel tank. The valve opens at approximately 97 kPa (14 psi).

Low Pressure Check Valves. Low pressure check valves are check valves used for low pressure applications. It include spring check valve, swing check valve, and wafer check valve. It allow fluids to flow in one direction only and prevent back-flow of fluids. Low pressure check valves are available in stainless steel material.

Knowing that the terminal pressure drop ratio for this particular model globe valve is 0.7 we can now predict that if the inlet pressure was 300 psi, flow would choke at 210 psi pressure drop (300 X 0.7 = 210). In order to properly size control valves for gas service, it is necessary to know at what pressure drop flow will choke.
