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 4" x 5" mud valves are stocked.
