Fully welded trunnion mounted ball valve (Cylindrical Type)
Structural characteristics:
- Fully welded structure, no potential bonnet connection leakage hazard
- Valve stem blow-out proof structure
- The use of raw materials that meet national standards can ensure the nominal pressure of the design
The valve seat sealing structure adopts a combination of spring load and enhanced PTFE to ensure tight sealing and long service life
- The stem is sealed with double O-rings, which can be replaced online
- The valve ball and stem are made of stainless steel to ensure corrosion resistance and increase service life
