Detailed measurements have shown that the power consumption of the OEM Actuator 5 is less than that of other systems – with some models running on just 1 W. The actuator needs up to 45 percent less electricity than its predecessor and other competing products. 

“Of course, this value depends on a number of factors such as the ambient temperature, operating voltage or air movement,” said Rainer Drescher, product manager for actuator technology at Möhlenhoff. “Nevertheless, every test has shown that the OEM Actuator 5 is far and away the most efficient on the market.” 

The OEM Actuator 5 uses an expanding element that is heated by a PTC resistor. The lower the temperature is, the better the flow of electricity through the material. The force produced by the movement of the expanding element opens and closes the actuator valve silently and without the need for any motor or gearing. With an actuating force of 100 N and a stroke of four or five millimeters, power consumption of just 1 W is all that is required. The larger actuator variants with a stroke of 6.5 mm and actuating force of 125 N consume 1.2 W.

These actuators are available for 24 and 230 Volt supplies, as wired-in or pluggable versions and in either normally closed (NC) or normally open (NO) variants. Proportional 0–10 Volt versions with valve stroke recognition and feedback channel are available for continuously regulated systems. Thanks to Möhlenhoff’s adapter system, the OEM Actuator 5 is compatible with practically all valve types. It is waterproof, takes up very little space thanks to its compact design and can be installed in any required position.
