What is an actuator operated butterfly valve?
An actuator is installed on the butterfly valve, enabling the valve to be controlled from a location other than its immediate vicinity. Both pneumatic and electric actuators can be installed on butterfly valves.
Selection of actuator operated butterfly valves
Pneumatic actuators are preferred in all but the largest sizes. They are available either as dual-acting, where compressed air both opens and closes the valve, or as single-acting (so-called spring-return), whereby on loss of pressure the actuator’s closing spring either opens or closes the valve.
Most of the market-available electric rotary actuator models are suitable for butterfly valves. All actuator options come with limit and installation data and can additionally be connected to a bus.
We assist in selecting and sizing an actuator-operated butterfly valve that meets the requirements of your application.
