Keystone Series GR Butterfly Valves
Keystone Series GR butterfly valves are designed for applications requiring drop-tight shut-off and maximum flow area, with features like field-replaceable seats and multiple shaft sealings.
- The seat is field replaceable and fully isolates the body and shaft from the flow.
- Primary and secondary shaft sealing prevent leakage.
- A molded-in O-ring eliminates the need for gaskets.
- Rounded polished disc edge provides full concentric sealing and longer seat life.
