Stem O-ring
  • Top bushing absorbs actuator side thrust loads.
  • Dirtscraper prevents moisture penetrating into the shaft area.
  • Actuator flange acc. ISO 5211.
  • High solid, glossy, silicone free, paint system ensuring excellent corrosion resistance.
  • Body locating holes ease installation and centering between the flanges.
  • Sealed body splits prevent moistures from penetrating behind the seat (up to DN 300).
  • Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and bubble-tight shut-off.
  • The seat is field replaceable and fully isolates the body and stem from the flow.
  • Primary stem sealing exceeds the pressure rating of the valve and prevents leakage through shaft area to atmosphere.
  • A secondary shaft sealing provides back-up safety.
  • A molded-in O-ring in the seat for flange sealing eliminates the need for gaskets.
  • The thin disc provides the very minimum obstruction to flow (up to DN 300).
