Features and benefits

  • Complies to API 602 and ASME B16.34 standards.
  • A compact but extremely sturdy design for high pressure-temperature service.
  • Available with bolted or welded bonnet.
  • Meets API 624 and ISO 15848-1 fugitive emissions standards.
  • Packing rings are pre-compressed in the packing chamber to ensure equal stress distribution, effectiveness of all rings and a high integrity seal.
  • For welded bonnet valves, the bonnet is threaded in and torqued to an engineered torque value and the body bonnet joint is strength-welded, offering double protection against leakage. (body/bonnet threads and strength-weld).
  • CoCr alloy hardfaced wedge (optional) ensures low friction and long service life.
  • Fully guided wedge reduces wear on seating surfaces.
  • For Class 1500 valves and for steam service, seats are seal-welded to the body.
  • Repairable two-piece stem drive.
  • Pre-positioned field injection ports for precise application of low emissions (Low-E) injectable packing through the bonnet (applies to bolted bonnet gate NPS 1/4–2 (DN 8–50) Class 150–1500).
  • Optional designs available with double packing, leak-off connection, live-loading, and packing blowout for easy removal of old packing.
