CU-ACT is a thermoelectric actuator used to open and close small valves on heating loops in a surface heating or cooling system. These actuators are mainly used in energy efficient zone-controlled systems. The actuator is connected to a 230 V
power supply and can be controlled using a two-point output or pulse-width modulation (PWM).

• Stroke length: 4.0 mm
• Closing force: 100 N
• Normally closed (NC)
• +/- 3.5 min OPEN/CLOSED running time
• Consumption: 2 W
