0-10V, Proportional actuator

The ABNM-A5 0-10V thermal actuator is designed for use with RA2000 thermostatic radiator valves in heating and cooling applications.

Control is done by a 0-10 V signal, which is provided either by a 3rd party room thermostat or, in most cases, by a central direct digital control (DDC) system. The actuator converts the 0-10 VDC signal into a proportional actuator travel to the RA2000 or RA-C series of valves.

Suitable applications for the ABNM-A5 actuator can include fan coil units, chilled ceiling applications, radiant floor heating or radiator valves. It is not recommended that the ABNM-A5 actuator be used on low pressure steam applications due to the increased temperature environment that the actuator is exposed to.
