WRAS Approved Electric Modulating Iron Butterfly Valves with AVA Electric Actuator




Wafer pattern butterfly valves sandwich between two mating flanges, secured by through bolts that pass all the way from one flange to the other, and a corresponding nut. See diagram to the right.
The correct alignment of wafer pattern valve so that the butterfly valve’s resilient liner seals against the raised faces of the flanges is aided by through-bolt lugs cast into the wafer valve’s body, although as these lugs are oval in shape to allow alignment with several different flange standards (ANSI, BS, DIN), care must be taken to ensure correct alignment when tightening the through bolts.
Wafer butterfly valves are not suitable for end of line service.


•Local controls with external OLED screen and push buttons.
•Fully weatherproof smart industrial actuator.
•Multi-voltage capable compact actuator.
•No need to remove the actuator’s main cover to connect electrically.
•Emergency manual override facility.
•Thermostatic anti-condensation heater.
•Electronic torque limiter.
•End of travel switches for remote open/ closed indication.
•Local mechanical visual position indicator.
•CE marked.


These WRAS Approved electric actuated wafer pattern cast iron butterfly valves use the AVA S60 electric actuator to provide proportional control in drinking water applications. Stays put if power fails. Supplied fully assembled and tested. You can buy electric actuated butterfly valves online at AVS.
