METAL SEAT BALL VALVES

There must be an alternate for soft seated ball valves because there are limitations of soft seated floating ball valves for certain applications like high temperature, abrasive, slurry. D valve has a wide range of high performance metal seated ball valves in floating design to overcome the above limitations of soft seated floating ball valves. The special coatings provided on ball & seat surfaces ensure reliability and durability in any severe service conditions. Precisely machined and lapped metal seat and ball combination guarantees good repeatability in performance. Two Pieces and Three piece metal seat Ball Valves are available.

Lip seal Design Metal Seated Ball Valves also available for Hydro carbon Applications.
