Electric Stainless Steel CF8M Metal Seated Ball Valve
Electric Stainless Steel CF8M Metal Seated Ball Valve
The
YFL metal seated ball valve adopts metal instead of Teflon and other soft seal
materials as seat materials to be suitable for high temperature
working conditions and severe service containing solid particles,
pulp, slurry, coal powder, mineral waste residue, ash, cinder etc.
The YFL metal seal ball Valve including floating
ball valve and trunnion mounted ball valve is widely used in industries of coal
chemical, petroleum, polysilicon, metallurgy, mining, paper etc.

- The SV high temperature metal seal ball
valve adopts ball and seat metal to metal seal structure;
- The ball and seat of SV
metal seated ball valve are hardened by supersonic spraying, nickel-based
spray, special face hardening, Tungsten carbide spray, ceramic materials etc.;
- Sealing face materials with good abrasion resistance and impact
resistance;
- The unique ball grinding technology makes the ball achieve
excellent roundness and finish to realize reliable sealing performance;
- The disc spring or spring loaded sealing structure absorbs the
thermal expansion of valve parts to ensure the ball valve opened or closed
easily without block under high temperature;
- The blade of valve seat on both sides can scrape the
solid-liquid mixed impurities bonded on the ball surface automatically to be
self-cleaning and ensure easy operation and good sealing performance;
- Added wear resistant busing in the channel of ball valve to
enhance wear resistance;
- Prevent incorrect operation structure;
- Anti-corrosion and anti-sulphur stressing cracking;
- Full bore and reduced bore;
- Floating ball and trunnion mounted ball;
- Double block and bleed for trunnion mounted ball;
- Bidirectional seal for double piston effect seat structure;
- Cavity automatic pressure relief for single piston effect seat
structure;
- Fire safe, automatic anti-static and anti-blowout stem design.
