TWA-Z Thermal Actuator

Brand: Danfoss

Danfoss thermal actuator TWA-Z is used with Danfoss automatically balanced combination valves type AB-QM. 

The actuator can be controlled with an on/off controller, pulse width modulation (PWM), or switch. 

These provide a cost effective solution for the control of hot and chilled water for fan coil units, small reheaters and recoolers in temperature control systems.
