Benefits

  • Special anti-rotation pin between valve disc and hanger arm prevents the seating area from changing as a result of occasional valve disc rotation.
  • Long-term tight shut-off due to uniquely designed screwed connection between valve disc and hanger arm enabling distance adjustment
  • Male/female joint between the body and cover prevents overtightening of the fully confined gasket, resulting in a longer gasket life and improved sealing performance.
