Vetec: Type R

Type R Actuator

The Type R Actuator is equipped with a rolling 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 very long travel ensures high torques and very fine control. Its special design allows the actuator to be used with different opening angles. The actuator can be equipped with additional manual overrides as well as end stops.
