1. Excellent design concept

The valve USES fixed ball two body to design, the cue USES the integral design, may guarantee the sphere to the neutral, causes the valve service life to have the guarantee, also causes the valve stem not to splash out. The ball is made of different materials, and the ball is made of different materials. The ball is made of stainless steel, and the valve stem is made of 17-4ph, which not only guarantees the material requirements of the ball hardening treatment, but also guarantees the strength of the valve stem.

2. Self-cleaning design

Scraping design, the valve seat adopts metal wideband self-scraping structure, can realize self-cleaning on the surface of the valve ball, prevent the ash and slag from blocking on the sealing surface.

3. Complete fireproof structure design

Inherent fire protection design, the sealing surface of the valve USES a metal to metal sealing structure, packing USES flexible graphite, gasket USES stainless steel + flexible graphite structure, therefore, the valve can ensure reliable sealing even in the case of fire.

4. Natural anti-static structure design

Metal hard sealing ball valve valve, body seat. Metal parts such as spheres are in close contact with each other, naturally forming electrostatic channels. Therefore, metal hard sealing ball valve does not need to set up a special anti-static device.
