  • The PTFE Liner itself is recessed into the valve body for added stability and to prevent possible leakage due to cold flow or improper valve installation
  • A backup elastomer in lay which energizes the body liner and provides the PTFE Flex – memory to assure long – lasting seat performance
  • Primary seal is achieved at the disc hub and PTFE liner (Ball & Socket) through preloaded force
  • Secondary stem sealing results from the use otan elastomer “O” ring which is tightly against the lined portion of the stem by the thrust ring
  • Triple stem seal system is uniformly loaded by a set of Belleville spring washers. Which maintains an active sealing force and self adjusts to changes in the system pressure and temperature
  • This triple stem seal design has proven to remain tight under the high thermal cycling life
  • Body and stem to fully protected against potentially dangerous electrostatic discharges
