Vetec: Type MD

Actuator Type MD

The Type MD Actuator is equipped with a diaphragm and several symmetrically arranged return springs.
The combination of several spring assemblies and the design of the piston rod bearing allow very high torques to be transmitted.
The short travel ensures very short actuating times.
The actuator can be equipped with additional manual overrides as well as end stops.
