BW Flanged Non Return Check Valve F4 GS-C25 Piston Lift Check Valve

DIN F4 GS-C25 Non Return Lift Check valve

Lift check valves are significantly custom-made for high-pressure service wherever speed of flow is high. In lift check valves, the piston disc is accurately target-hunting by long contact and an in depth sliding work with the peerless targeted dash pot. The walls of the piston and dash pot are of roughly equal thickness. Giant steam jackets are placed outside of the dash pot and within the piston to eliminate sticking out due to differential enlargement. The seat ring is of a barrel sort design of significant uniform crosswise. It’s commonly screwed in and seal welded. The flow gap is full port size.

The seat design of a lift-check valve is comparable to a globe valve. The disc is typically within the type of a piston or a ball. The ball-lift check valves are employed in extremely viscous fluid service. These check valves have superior leak-tight feature to those of swing check valves.

The piston kind lift check valves have an inclination to stick within the open position once service fluid has sediment treed on top of the piston. Giant lift check valves are equipped an equalizer line between the chamber on top of the disc and therefore the downstream aspect of the valve.
