Feedback signal permits remote maintenance

Möhlenhoff presents the first thermal actuator with feedback channel

Salzgitter, April 2015. – Thermal actuators, for example as used in underfloor heating or building control systems, always have to satisfy exacting requirements: They must deliver outstandingly accurate regulation, operate efficiently and reliably and, in combination with the valve, permit rapid, uncomplicated maintenance. Möhlenhoff GmbH, the global market leader for thermal actuators, has recognized this trend and extended its proven “OEM Actuator 5” product family to include a unit featuring an integrated feedback channel. In this way, users can check the current valve position quickly and easily even when they are not on site.

The “OEM Actuator 5: 6.5 mm DDC” with feedback channel is perfect for opening and closing standard and line valves, balanced valves, as well as manifold valves for heating and cooling applications. It possesses an actuating force of 125 newtons and a stroke of 6.5 millimeters. This ensures exceptionally accurate regulation – because a larger stroke at the valve results in a more finely graduated control circuit. The actuator is controlled using a 0-10 volt control voltage.

As the first thermal actuator on the market, the “OEM Actuator 5: 6.5 mm DDC” is available with integrated feedback channel. An additional line allows users to tap a signal with a voltage of 0-10 volts that indicates the current valve position. This can be compared with the control voltage applied at the actuator – either on site or by means of a remote query. If the feedback signal mirrors the control voltage then the actuator and valve are functioning correctly. The benefits of the “OEM Actuator 5: 6.5 mm DDC” with feedback channelwhen used in combination with a valveinclude significantly faster, simpler maintenance and lower procurement costs. In the past, valve actuators with feedback signal or feedback channel were only available for considerably more expensive, motor-driven applications.

Thanks to Möhlenhoff’s unique adapter system, the new OEM drive is compatible with practically all valve types. It features all the advantages that characterize the other members of its product family: It is extremely robust and durable, waterproof in any installation position, and takes up very little space thanks to its compact design. Equipped with a thermal element, the actuator operates without a motor or gearing and is therefore absolutely silent and particularly energy-efficient. The product range includes a normally closed (NC) and normally open (NO) variant. The actuator also possesses a removable dismount protector.
