Series 61W (wafer) and 61L (lug) are resilient seated butterfly valves suited for applications within the water; wastewater and general industrial markets.
Series 61W (wafer) and 61L (lug) are resilient seated butterfly valves suited for applications within the water; wastewater and general industrial markets.
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 stem area to atmosphere.
- A secondary stem seal provides backup sealing.
- Top and bottom inboard stem 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 stem area.
- A molded-in O-ring in the seat for flange sealing eliminates the need for gaskets.
- Extended body neck allows for pipe insulation.
- Body locating holes ease installation and centering between the flanges.
- Available approvals: PED (CE Mark), DNV, Lloyds.
