Clamping ultra-thin check valve is a disc type ultra-thin check valve, using short structure size and single disc design, disc with O sealing ring, sealing performance is good, and the spring auxiliary close, the action is sensitive, especially for the installation of space restrictions most suitable for the place.
It has the advantages of simple structure, beautiful appearance, light weight and convenient installation.
Mainly used in water supply system, petroleum, chemical industry, metallurgy and other fields.
1. Reasonable product structure, reliable sealing, excellent performance and beautiful appearance;
2, the surface welding Co base hard alloy, wear resistance, corrosion resistance, abrasion resistance, long service life;
3. The built-in pin shaft structure reduces the leakage point and ensures reliable use;
4. When the pressure is ≥ 16.0mpa, the valve cavity adopts self-tightening sealing structure. The higher the medium pressure is, the better the sealing performance will be.
5. The material, flange and butt welding end size of the parts can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
