On-Off & Modulating Duty
DREHMO actuators are available in 3 types of duty:
- On-Off duty: Actuators for on-off duty (short time duty S2) mostly operate shut-off valves with only a few open-close cycles.
- Inching duty: Actuators for position operation drive to the limit positions as well as to the intermediate positions and therefore measures the position of the valve continuously.
- Modulating duty: Actuators for modulating duty in combination with the valve control values such as temperature, pressure and flow rate. They are designed for intermittent duty S4 acc. to VDE 0530.
