- keystone气动蝶阀F611F79U791CR
- F611 Wafer style resilient seated butterfly valves.
- F612 Lugged style resilient seated butterfly valves.
Features & Benefits:
- 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.
