Description

  • ZSHOY/ZDROY Series metal seated ball valves, two pieces design in small size, and three pieces design in large size. The ball is a full bore so that large capacity and small flow resistance. The ball is available with Nickel base alloy and tungsten carbide hard coating to have good abrasion resistance; Seat is overlaid with cobalt-base alloy and hard alloy to improve seal performance and extend the service life. Our metal seated ball valves included the electrically operated ball valvesand pneumatic ball valves, are used in petroleum, petrochemical, metallurgy, pulp and paper, scaling, coking, polymerizing, or other similar industrial processes.

Features:

  • The off-center split body design allows the use of advanced spiral wound gaskets.
  • Full port ensures large capacity and reduces the risk of clogging when handling solids or slurries.
  • All valves with graphite packing and backup seal are fireproofing.
  • Ball and seats lapped for optimum performance and tight shutoff.
  • Anti-blowout stem.
