API 6D Swing Check Valve with Lever counter weight

RSF VALVE is one of leading professional industry valve manufacturer from China. Our API 6D fully open swing check valve is one kind of non return valve of oil and gas industry valves. The non return swing check valve allows the fluid to flow only in the desired direction. The globe check valve design is such that any flow or pressure in the opposite direction is mechanically restricted from occurring.

RSF VALVE API 6D Swing Check Valve with pneumatic actuator is used to prevent backflow of fluid, which could damage equipment or upset the process. The nonreturn swing check valve 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. The API 6D cast steel Swing check valve with pneumatic actuator is also applied in process systems that have varying pressures, which must be kept separate.
