Operating Principle
The stainless steel shut-off and switching valve can be opened through the handle and is composed of few disassemblable parts. It comes with simple structure and open support that sets the pneumatic actuator apart from the valve body. The special structure allows direct inspection of the seal and guards against thermal transmission from the body to actuator. The standard design assures longer service life of the seal, rapid installation and handy maintenance.

Features
With elastic structure, its flashboard does well in sealing. The sealing sides of the flashboard and valve seat employ stellite cobalt-based hard alloys with distinctive stiffness, which is conducive to good sealing performance, high stiffness and long service life, and enables them to resist wear, high temperature, corrosion and scratch.
