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

Deployed as:

  • Retainer Valve
  • Safety Head Valve
  • Production Isolation Valve

The 7-3/8” Entegrity Shear and Seal Gate Valve uses metal-to-metal sealing ensuring superior integrity at higher pressures and wider temperature ranges than conventional ram shear valves. The Entegrity 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.
