Shear & seal gate valve with bi-directional, metal-to-metal sealing

Deployed as:

  • Retainer Valve
  • Safety Head Valve
  • Production Isolation Valve

The 7-3/8” En-Tegrity Shear & Seal Gate Valve uses metal-to-metal sealing ensuring superior integrity at higher pressures and wider temperature ranges than conventional ram shear valves. The En-Tegrity sealing gates, isolated from the cutting blades, guard against any cut materials interfering with the seal integrity, safeguarding future well interventions*.

*Subject to cutting media being in tension.
