La selección de materiales es exquisita, de acuerdo con los estándares nacionales y extranjeros pertinentes, y los materiales son completos y de alta calidad.
The matching of sealing pairs is advanced and reasonable, and the sealing surface of the valve stem and valve seat is made of iron-based alloy or stellite
(Stellite) cobalt-based cemented carbide surfacing. Good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.
Various standard sealing types of piping flanges can be used to meet various engineering needs and user requirements.
The valve body material is complete in variety. Gaskets can be reasonably selected according to actual working conditions or user requirements. It can be applied to various pressure, temperature and medium working conditions.
The valve clack rotates around the pin shaft outside the valve seat to reduce the violent impact when closing.
The connection between the pin shaft and the disc adopts a built-in structure, there is no external leakage point, and the use is more reliable.
