Keystone 221 Series Wafer Style Butterfly Valves

Keystone Series 221 Wafer Style Butterfly Valves feature rugged quality construction. Lockable handles. Maximum flow area for use in on/off as well as throttling control applications. Valve bodies are cast iron and the standard seat is EPDM with Buna available (both FDA rated). The bonded seat is designed to completely isolate the valve body parts from the liquid. Rounded, hand-polished disc and hub edge give full concentric seating without seat obstruction, providing maximum seat life.

These valves also feature bubble-tight shut-off, with body locating holes for easy installation and centering between flanges. They have resilient, molded-in non-replaceable seats; suitable for full vacuum applications. (For buna seals add “B” suffix). Manual gear operation available on -80G, -100G.
