Wafer Butterfly Valve, NBR Seat, Nickel Disc, Pneumatic Actuator

This wafer butterfly valve combines an NBR seat, nickel-plated disc and pneumatic actuator for compact, reliable flow control in water, wastewater, air and gas lines. It installs between two flanges and is not suitable for end-of-line service. Choose a double-acting (DA) actuator or a spring-return single-acting (SA) model for remote automated operation. With an SA actuator, the spring returns the valve to its configured fail-safe position when air is lost; a DA actuator uses air pressure in both directions. Solenoid valves and limit switch boxes are available as accessories.
