  • Thermodisc* technology compensates for temperature gradients around the seating surface for a high degree of seat tightness and a low spindle bearing point.
  • Supports proper alignment and load distribution at the seating surface.
  • Thermodisc design reduces disc sliding across the seat while it is actuating.
  • Single blowdown ring makes it possible to set and test a valve that has been in service.
