Keystone Butterfly Valves, Wafer/Lugged, Resilient Seated, Keystone Series 61 Resilient Seated Butterfly Valve

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.
