ALRE ZBOOA-040.100 Valve Actuator 24V DC/AC Normally Closed 100N

The ALRE ZBOOA-040.100 is a reliable valve actuator designed for 2-point (on/off) control of heating and cooling systems. Operating on 24V AC/DC, it delivers a 100N actuating force with a 2.5mm stroke, ensuring precise valve positioning. The actuator features a normally closed (NC) fail-safe function, meaning the valve closes automatically in case of power loss, providing safety and energy efficiency.

Advantages

This actuator offers robust performance with a running time of approximately 120 seconds for full stroke. Its compact design and M30 x 1.5 threaded connection make it compatible with a wide range of valves. The visual position indicator allows for easy status checking, while the 1.0m cable with 3 x 0.75 mm² conductors simplifies installation.

Suitable for

• Heating and cooling systems requiring 2-point control
• Underfloor heating manifolds
• Radiator valves with M30 x 1.5 connection
• Building automation and HVAC applications
