Features

  • Full round port, adaptable to match specific pipe I.D.s offers lowest possible pressure drop across valve and longer service life in abrasive applications.
  • Shut-off conforms to the requirements of ASME Class V.
  • True bi-directional flow and shut-off, can be installed in either direction.
  • Designed as a field repairable asset for a lower overall cost of ownership.
  • Heavy cross section precision molded urethane seat, simple to replace, no shimming or trimming.
  • Seat is held in place by the bolted body to prevent pullout or shifting in the body.
  • Cast bolted body available in CF8M, 2507, WCB/LCB or other materials.
  • Polymer chest liners to support gate through the full length of the stroke.
  • Two styles of replaceable and rotatable integral flow rings available: Internal rings are suitable for dead-end service; External rings are not for dead-end service.
  • Superior packing assembly is standard with live-loaded gland studs, providing continuous load.
  • No special tools or unique packing materials to maintain or replace packing, can be repacked with valve in-line (line pressure must be relieved).
  • Gate is standard with SSEC, formulated to improve abrasion resistance and extend seat and packing life. Other gate materials available.
