Vetec - Model Type MZ -Pneumatic Diaphragm Actuator
The Type MZ Actuator is equipped with a diaphragm and a centrally arranged return spring on the inside. The freely supported piston rod is directly connected to the lever for the valve shaft. The short travel ensures very short actuating times. In addition, the actuator is designed for very fine control. The actuator can be equipped with additional manual overrides as well as end stops. For automatic actuation of industrial valves. e.g. rotary plug valves, ball valves, butterfly valves.
