Check valves are used in
pipes under pressure between PN1.6～PN*6.0 MPa (Class**0～Class***0),
working temperatures≤**0℃ in oil, chemistry,
pharmaceutical, fertilizer and power station to prevent the
backward flow of the media.
1. The
products feature a reasonable structure, reliable seal, good
performance and nice modeling.
2. Soft
or hard seal can be selected for the product upon different working
conditions. The sealing face is built up with Co based carbide
alloy, which is wearing resistant, erosion proof, abrasion
proof and long use life.
3. Small
opening pressure, the disc can be opened fully with a very small
pressure.
4. Inside-set
bolt-bearing structure reduces leakage and reliable use.
5. PN≥*5.0
MPa (Class***0), the middle cavity uses a self-tightening seating
structure to have the sealing performance reinforced along with the
pressure rise so as to ensure the sealing performance.
6. The
body material and the end dimension can be selected and machined
according to the applications and the requirements of the user’s.
That can satisfies all kinds of working requirements.
