SIRO Stepper Motor NC Advantage Package 1

230V NC Mini actuator for heating valves

The SIRO Mini actuator uses an advanced wax-PTC element for virtually silent operation and long-lasting reliability. As a compact heating actuator, it blends inconspicuously into any system installation and ensures trouble-free valve movements.

Precise control with travel distance and position display.

With a 4.5 mm stroke and a maximum tensile force of 110 N, this valve actuator enables precise control of thermostat and 2/4-way valves. The integrated position indicator clearly displays the current travel path at all times and ensures maximum control.

Automatic spring return in case of power failure

The integrated spring return function closes the valve immediately as soon as the power supply is interrupted. This NC actuator thus provides reliable protection for your underfloor heating circuit and prevents unwanted flooding in the event of a power failure.

Robust IP54 protection rating and double insulation

Designed to protection class II with double insulation and an IP54 housing, the mini actuator withstands dust, splashing water and humid environments. This high protection rating makes the actuator ideal for long-term use in heating and industrial environments.

Compact design and easy assembly

With dimensions of only 62 × 30 × 39 mm and a 100 cm connecting cable, the actuator fits even into tight back spaces. The tool-free mounting via nut connection enables quick replacement and uncomplicated installation without special tools.
