The main advantage of the actuator is its versatility – thanks to the use of the most popular M30 x 1.5 thread, it fits most manifolds and thermostatic valves available on the market. A robust construction and high IP54 protection rating guarantee safe and trouble-free operation even in difficult conditions that may exist in manifold cabinets. The actuator is characterised by very low power consumption of just 2W, making it an extremely energy-efficient solution while maintaining an optimal thrust force of 105N.
Installation of the device is quick and intuitive, and the long, 70 cm power cable allows for easy connection to a control strip or room thermostat. Quiet operation and smooth opening and closing (cycle time of approximately 3 minutes) eliminate the risk of hydraulic shocks in the system, which additionally protects the entire heating system from premature wear. By choosing this actuator, you are investing in reliability and intelligent heat management in your home.

The thermoelectric actuator is an advanced device designed for precise flow control in surface heating and radiator systems. It is a key component of modern home automation, allowing for the automatic closing and opening of heating loops in manifolds, which translates into significant energy savings and increased thermal comfort in rooms. The device operates in NC (normally closed) mode, meaning that without power, the valve remains in the closed position.

Application
Automatic control of valves on underfloor heating manifolds, radiator valve control, compatibility with wiring centres and room thermostats.
Technical characteristics
The actuator uses a thermal (wax) element that expands under applied voltage, causing the stem to move. This process is intentionally slowed down to ensure stable operation of the hydraulic system. The device is maintenance-free and designed for continuous operation in building automation systems. Thanks to the IP54 ingress protection rating, the actuator can be mounted in any position, although vertical or horizontal mounting is recommended for optimal durability.
Electrical interface
2-core cable, allowing direct connection to 230V controllers without the need for additional transformers.
