WKM Expanding Gate Valve

WKM Expanding Gate Valve introduction

  • Nominal size: 2-1/16"~7-1/16" (46mm~180mm)
  • Working temperature: - 46℃~121℃(LU)
  • Material class: AA、BB、CC、DD、EE、FF
  • Specification level: PSL1-3
  • Performance Requirement: PR1
  • Working medium: oil, gas, mud, gas contain in H2S、CO2
Features and Benefits:
  • Metal-to-metal sealing (gate-to-seat and seat-to-body).
  • Expanding gate design creates a positive mechanical seal across the seats, with or without line pressure.
  • Full-bore, through-conduit gate-to-seat seal maximizes valve life by virtually eliminating turbulence and pressure drop.
  • Gate skirts reduce loss of body lubricants.
  • Low running stress enhances life of the gate-to-seat interface.
  • Upper/lower roller thrust bearings are isolated from well fluid, minimizing torque.
  • Stem packing can be re-energized with valve under pressure.
  • Non-rising stem permits valve installation in closer quarters.
  • Seats, gates, stem, and other working parts are field replaceable.
