Wafer Lift Check Valve

 

GZP WAFER LIFT CHECK valves are manufactured according to the latest editions of API 602, BS 5352, and ASME B16.34 standards, and tested by API 598. All forged steel valves from GZP VALVE undergo rigorous 100% testing before shipment to ensure zero leakage.

 

GZP VALVE, a leading manufacturer, factory, company, and supplier of spring-loaded lift wafer check valves in China, offers valves with exquisite profiles and simple structures. The spring mechanism accelerates the closing movement of the disc, effectively eliminating the water hammer. This valve is very suitable for space-limited locations.

Structural Features of Spring-Loaded Lift Wafer Check Valves:

1. Compact size, lightweight, and easy to maintain.

2. Smooth operation without vibration or noise.

3. Excellent sealing performance, ensuring no leakage.

4. Impressive opening and closing capabilities. Opening pressure ≤ 0.08 MPa; quick opening and adjustable closing speed. The closing movement consists of two stages: an initial rapid closing followed by a slow, adjustable closing.

 

Additional Benefits:

● Low-Pressure Drop (High Cv)

Our elastomer hinge check valves feature a larger open area than other designs, providing higher capacity and lower pressure drops compared to swing and lift check valves or even traditional dual-plate wafer designs.

● Lightweight

Reduces weight by 80-90% compared to conventional flanged check valves.

● Water Hammer Mitigation

When spring-activated, our discs close 33% faster than standard dual-plate wafer check valves due to their 30-degree closing angle. This results in an effective non-slam design suitable for liquid applications.

● Simple Installation

Easier to install, remove, and replace in both new and existing piping systems.

● Variety of Configurations

We offer a wide range of wafer bodies in different styles and materials. These can be assembled with our standard discs, optional springs, and elastomer seals to create a valve tailored to your specific application. Pins and hardware are always made of 316SS.
