Check Valves
Wafer Lift Check Valve supports reverse-flow control. Selection focuses on the sealing arrangement, fluid conditions, piping interfaces and operating requirements.
Configuration and suitability depend on the specific model documentation.
A check valve opens and closes automatically in response to fluid forces to restrict reverse flow. Its behavior depends on disc motion, velocity, differential pressure and installation orientation. Selection should consider flow changes and pump shutdown, balancing forward pressure loss against closing response.
A lift arrangement opens and closes through guided disc movement. Reseating may rely on gravity, a spring or reverse differential pressure, which determines orientation requirements. Check opening differential pressure and disc stability at low flow.
Wafer installation places the valve between mating flanges. Check flange standard, pipe bore, bolt arrangement and clearance for moving internal parts. Additional gasket requirements depend on the seat and connection design.
Define fluid composition and continuous and start-stop operating conditions, then assess body, internals and seals as a combination. Particles, deposits and cleaning affect sealing surfaces and mechanisms; plan maintenance for the actual service.
