BR 30a - Pneumatic rotary actuator

The Type BR 30a single-acting pneumatic diaphragm multi-turn actuator is designed for butterfly valves and other rotary valves.

The pneumatic Series 30a multi-turn actuators are diaphragm actuators with rolling diaphragm and centrally arranged return springs. The signal pressure generates a force at the diaphragm surface which opposes the compression springs arranged in the actuator. The travel of the actuator shaft is transmitted via a lever mechanism onto the drive shaft.
