The BS5153 Ductile IronMetal Seat swing check valve is onekind of Non Return Valve of waterworks valves. It allows the fluid to flow only in the desired direction. Thedesign of check valve is such that any flow or pressure in the oppositedirection is mechanically restricted from occurring.
TheBS5153 Ductile Iron Metal Seat Swing Check is used to prevent backflow offluid, which could damage equipment or upset the process. The BS5153 gunmetalseat swing check valve is especially useful in protecting a pump in liquidapplications or a compressor in gas applications from backflow when the pump orcompressor is shut down. The non return Swing check valve with lever and weightis also applied in process systems that have varying pressures, which must bekept separate.
The RSFBS5153 ductile iron metal seat swing check valves are installed on pipeline ofpump outlet for prevent the media reflow and the pressure rise overlarge (waterhammer) which caused by reflow closing. Our check valve with hydraulic damperis one kind of water works valves which is widely used in water pipe system.
As wellas the BS5153 Ductile Iron Metal Seat Swing Check Valve, our non return valveseries products includes WaferCheck Valve, Double Check Valve, Ball Check Valve, tilting check valve, nozzle check valve, etc.
