Stainless Steel Hard Seal Flange Ball Valve:WCB,DN100 1/2″-8″

Jan 01, 1970

Stainless steel hard seal ball valve whoes sphere and valve seat use metal to metal seal.The sealing structure loaded flexure spring used in the valve seat pushes through the limitations of low operating temperature for soft sealing ball valve and not applicable for media with granular. Stainless steel hard seal ball valve is used in the equipment and pipeline for high temperature and high pressure water, steam, oil, viscosity and particle media.

[Features]

- The plate spring loaded sealing structure used in the valve seat can be used in a higher temperature and media with granulars.
- The ball can be designed as an anti-static structure. Conductive spring is arranged between the ball and stem to avoid igniting the flammable material static spark for static sparking, and to ensure systems security.
- Ball valve seat can be arranged auxiliary seal structure. Adding grease valve in the place of the valve seat and the stem can be temporarily sealed for emergency situations , and the stemcan be extended to be for beuried and laying places according to needs
