Radiator Thermostats

Electric valve actuators

 


Thermal Wax
Actuator, TWA

Thermal Wax<br>Actuator, TWA
TWA actuators are used to electrically activate valves on hot water heating systems, where slow opening and closing is desirable to eliminate water hammer associated with quick acting valves.

ABNM Actuator

ABNM Actuator
ABNM modulating valve actuators are used in direct digital controlled (DDC) systems with 0-10 V DC control voltage.  The ABNM design offers precision regulation, long life, silent operation and full valve modulation.

ABRA Actuator

ABRA Actuator
ABRA actuators are used to electrically activate valves on hot water heating systems, where slow opening and closing is desirable to eliminate water hammer associated with quick acting valves.
