Features

1.Valve stem anti-fly out structure

 

2.Anti-static device: an anti-static device is set on the valve to export the generated static electricity

 

3.Fire prevention structure: when the non-metallic sealing surface material burns out in a fire, the metal ring USES the spring's spring force to push the valve seat and seal the ball, so as to prevent the fire spreading and medium flowing out.

 

4.Middle flange no leakage structure: the connection between the valve body and the left body is cushion piece seal, specially designed for the valve body and the left body metal contact, the formation of check flange, to ensure no leakage.

 

5.Automatic pressure relief structure: when the pressure in the middle chamber rises abnormally, the medium in the chamber can push the valve seat with its own thrust and automatic pressure relief, so as to ensure the safety of the valve.
