  • products details
YFL Metal Seated Ball Valves with harden ball and metal seat are suitable for working conditions with high temperature. YFL metal seated ball valves also solve abrasion problems in abrasive slurry containing solid particles like paper pulp, mining slurry, coal powder, mineral waste residue, ash, cinder etc.

YFL metal seated ball Valve features:

1. Ball and seat hardened by spraying welding with Nickel-based alloy, Tungsten carbide or CrC to be wear resistant and high temperature resistant;
2. Ball grinding makes the ball achieve excellent roundness and surface to realize excellent sealing with seat;
3. The disc spring and spring loaded sealing structure absorbs the thermal expansion from valve parts to ensure the ball valve can be open or closed easily without block in high temperature working conditions;
4. The valve seat blades scrape the residues on the ball surface automatically to be self-cleaning and ensure smooth operation and excellent sealing performance;
5. Wear resistant bushing in the flow channel enhances wear resistance against abrasive solids
6. Full bore and reduced bore available;
7. Floating ball and trunnion mounted ball available;
8. Fire safe, anti-static and anti-blowout stem design;

YFL metal seated ball valves are widely used for projects with abrasive medium and high temperature in industries of coal chemical, petroleum, polysilicon, metallurgy, mining, paper etc.
