Thermal actuator TWA-A NC 230V, 1.2m 088H3112

Thermal actuator for valves – reliable heating control

This thermal actuator, catalog number 088H3112, is a wax-filled technology component designed for automatic control of radiator valves. It is suitable for both domestic and more demanding heating systems. It is compatible with Danfoss VMT, RA and RAV valves, as well as products from other manufacturers (Heimeier, MNG, Oventrop) thanks to available adapters.

Practical solution for installers and users

The TWA-A NC 230V actuator is a simple to install and operate device that provides precise temperature control in rooms. Its normally closed (NC) function means that the valve remains closed in the event of a power failure – which is important from the point of view of safety and energy saving. A built-in position indicator allows for quick visual control of the actuator status.

Construction features and operating parameters

The actuator operates at 230V AC and is characterized by low power consumption – an average of 2W during operation and a maximum of 7VA. The actuator transition time is approximately 180 seconds (3 minutes), ensuring smooth and comfortable temperature changes. Made of high-quality materials, in white color, it has a protection class of IP41 – which means resistance to the ingress of solid objects larger than 1mm and to condensation. The cable length (1.2 m) provides installation freedom without the need for extension cords. The device is adapted to work in an ambient temperature from 0°C to +60°C. The actuator diameter is 40.5 mm, and its dimensions are 70 mm wide and 91 mm high. The control signal is two-point.
