Thermo-elektrische actuator STT-230/2 T M30x1.5 Tech Sterowniki

The Tech Sterowniki STT-230/2 T M30x1.5 is a high-quality thermoelectric actuator designed for precise control of underfloor heating manifolds, radiator valves, and zone valves. Operating at 230V AC with a normally closed (NC) function, it ensures reliable shut-off when de-energized. The actuator features a compact, self-extinguishing plastic housing with IP54 protection, making it suitable for demanding environments.

Advantages

This actuator offers silent operation, low power consumption (2W), and a quick response time of approximately 120 seconds. The visual position indicator (red) provides clear status feedback. Its M30x1.5 mounting thread ensures compatibility with standard valve bodies.
