API 594 Dual Plate Check Valve

We are a leading manufactuer of oil and gas industry valves, we have more than 15years experience in producing cast steel API 594 Dual Plate Check Valve ( wafer check valve, lug, flange and BW ends), API 600 gate valve, BS1873 globe valve, non return valve of BS1868 swing check valve, ball valve, butterfly valve, et. 

RSF’s API 594 Dual Plate Check Valve is one kind of important non return valve. It allows the fluid to flow only in the desired direction. The design is such that any flow or pressure in the opposite direction is mechanically restricted from occurring.

RSF's non return valve of API 594 Dual Plate Check Valve is used to prevent backflow of fluid, which could damage equipment or upset the process. The dual plate wafer check valve (lug, flange, BW) is especially useful in protecting a pump in liquid applications or a compressor in gas applications from backflow when the pump or compressor is shut down. Swing check valve is also applied in process systems that have varying pressures, which must be kept separate.
