Design Features

  • A compact but extremely sturdy design for high pressure temperature service.
  • Solid CoCr alloy wedge (optional) ensures low friction and long service life.
  • For Class 1500 valves and for steam service , seats are seal-welded to the body.
  • Packing rings are precompressed to 4000 psi to provide a high intergrity seal.
  • For welded bonnet valves, the bonnet is threaded in and torqued to an engineered value and the body bonnet joint is strength welded, offering double protection against leakage. (body/bonnet threads and strength-weld).
  • Fully guided wedge reduces wear on seating surfaces.
  • Repairable 2-piece stem drive.

Optional Features (Special Applications)

  • A special design is also available with double packing, leak-off connection, live-loading and a packing blowout for easy removal of old packing.
  • Bolted Bonnet gate valves for alkylation service.
  • Parallel slide gate valves.
  • API 603 NPS 1/2 – 1 1/2 (DN 15-40), for ASME Classes 150, 300 and 600.
