The Motoric Valve Drive: 24 V Proportional failsafe is an electromotive actuator for opening and closing valves for heating and cooling systems. The predominant area of application is the energy-efficient control of water-bearing valves in the area of building services and automation. The actuator is equipped with a failsafe function. If the power supply fails, the valve pressure plate moves into a parking position. The energy for this is provided by an internal rechargeable accumulator.
The control is performed by a 0-10 V DC control signal sent by a central DDC system or a room thermostat. The current position and the control voltage are shown on an LC display.
The actuator supplied with a pluggable connecting cable has a manual valve adjustment which can be used, for example, for maintenance or installation. A version with feedback signal is available as an option. The back channel transmits information about the current valve position as well as about possibly occurred errors to the DDC installation.
