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.

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

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.
