• 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 seal provides back-up safety.
• Top and bottom inboard shaft bearings for optimum support and minimum friction to prolong valve life.
• Top bushing absorbs actuator side thrust loads.
• Top seal prevents moisture penetrating into the shaft area.
• The thin disc provides minimum obstruction to flow, resulting in smooth flow characteristics.
• A molded-in O-ring in the seat for flange sealing eliminates the need for gaskets.
• Extended body neck allows pipe insulation.
• Body locating holes ease installation and centering between the flanges.
• Available approvals: PED (CE Mark), DNV, Lloyds.
