Wafer CheckValve

The wafer check valve is used in PN1.0MPA-42.0MPA
Class150-2500.DN15-DN1200,NPS1/2-48.
Working temperature-196-540 deg etc, many kinds of pepelines,which can prevent the refluence of medium, and can beapplicable to water, steam,oil.nirticacid, high oxidizability mediums,ureaand so on , via choosing different types of materials

Main materials: carbon steel, low temperature steel ,dual phase steel, titaniumalloy, aluminum bronze, INCONEL, stainless steel, chrome-molybdenum steel , monel(400/500),20#alloy, haynesalloy etc.

Design feature
1. Short length structure, which is only 1/4-1/8times thelength of conventional flange connecting check valve.
2. Small volume and light weight
3. Quickly closed by the disc,smellpressure of hammer blow,
4. Which can be used in horizontal pipeline or vertical pipeline, and also hasconvenient mounting.
5. Very nice flow channel and small fluid resistance, yare acting and bestsealing, short journey odthe disc, small impact force of closing. Integral structure, simple and compact,beautiful sculpt, long life of using, high reliability.
