Model 8000F Isolation Valve is designed to incorporate two safety relief valves to protect in an over-pressure emergency. Only one safety relief valve is in operation while the other is a back-up. If a problem occurs, such as a leak, simply switch to the other safety relief valve and remove the faulty one and make repairs. This insures that one safety relief valve is in operation at all times.

  • Automatic pressure balance at start of position change.
  • Pressure bleed valve at each position also serves for in-line testing.
  • Locking device permits valve to be locked in operating position only. (Optional)
  • Low profile design for easy installation in tight areas.
  • External position indicator shows which safety relief is in operation.
  • Double sealed selector assures over-pressure relief protection at all times.
  • Standard o-ring seating keeps maintenance cost to a minimum.
  • Two-piece body allows for replacement of isolation valve seals without removal of safety relief valves from body.
  • Low-pressure drop permits maximum SRV performance. CV factor (stem end) provided to assist in selection of proper isolation valve to conform to API RP 520 Part 2 Section 2.2 recommended practices.
  • Sizes ½” ¾”, 1”, 1 ½” and 2”.
