Piston Lift Check Valve Forged Steel A105 1Inch Dn25 600lb Professional Oxygen Vertical Lift Rf Nrv Check Valve
VERVO Piston and ball check valves, like all check valves, are used to pre- vent back flow in the line. ... In Piston, or lift, check valves a body-guided disc moves within the body bore. The body guide ensures alignment of the seat and disc when the valve closes.
PISTON CHECK VALVE The pressure of the fluid passing through a system opens the valve, while any reversal of flow will close the valve. In Piston, or lift, check valves a body-guided disc moves within the body bore. The body guide ensures alignment of the seat and disc when the valve closes. The valve is installed with the flow under the disc, so that the inlet line pressure and flow rate will force the disc to “lift” off the seat and allow the line fluid to flow through the valve. Should the flow suddenly reverse itself, the disc will automatically and quickly, assisted by the weight of the disc, be forced to the closed position, preventing the line fluid from returning. Exercise caution when these valves are used for dirty media because that media could cause the disc to stick inside the body bore.
BALL CHECK VALVE The function of ball check valves is similar to the piston check, but the ball check valves use a “ball” inside the body to control the movement of flow. The ball is free to rotate, resulting in even wear and a wiping action between the ball and seat. This feature makes ball checks useful for viscous media.
