PISTON CHECK VALVE The pressure of the fluid passing through a sys-tem 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


※ Piston Check Valve Manufacturer. CATALOG enquiry. Specifications. The main advantage of the piston check valve has simple structure. Since the conical valve flap is the only moving part, the valve is sturdy and durable and require little maintenance.


Piston Check Valves. The fluid pressure that passes through a device opens the valve whereas the valve is closed by any inversion of flow. Piston, or lift check valves use a body-guided disk which moves inside the body up and down. The body guides guarantee the proper alignment of the seat and disk configuration when the valve is closed.
