The Premium Oilfield Technologies NV75 Mud Gate Valve is a full metal to metal sealing gate valve for use in applications up to 7500 psi. The NV75 uses single piece seat rings creating an upstream metal to metal seal. The upstream design helps eliminate debris contamination into the valve body and reduces wear on the internal components.

  • Single Piece Seat/Belville Spring design
  • Metal to Metal Sealing
  • Upstream sealing (Reduced solids in valve cavity)
  • Interchangeable Demco upper section (Bonnet)
  • Special Urethane stem packing
  • Stainless steel stem, gate and seats. Forged bonnet
  • Certs available up to API PSL-2

Applications:

  • 7500 PSI Mud Systems
  • Standpipe Manifolds
  • MPD Manifolds
  • Bleed Lines
  • 2” and 4” Full Bore, 1502, BWP or Flanged

Features:

  • Designed to be repaired without taking valve offline. This is accomplished through our removable bonnet design.
  • Seats are made with a long lasting elastomer that is bonded to two stainless steel inserts and a locking device that insures proper alignment when installing the seat.
  • Replaceable seat rings that wear instead of the valve body, thus extending service life of the valve.
  • Valves and our repair kits are 100% interchangeable with our competitors on a part to part and unit to unit basis.
  • Stainless steel trim is standard on all valves, for high performance in corrosive applications.
  • Major and minor spare parts kits for 1.5", 2", 3", 4" and 5" mud valves are stocked.
