Pneumatic valves

Motorised valves are ball and butterfly interception valves, with an apparatus that permits remote closing and opening by way of an electric or pneumatic actuator. The pneumatic actuator transmits movement to the valve using compressed air as the movement fluid. Pneumatic actuators can be double or single effect: in the first case it is the air that opens and closes, while in the other case closing is controlled by a spring.
