Electric zone valve actuators

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

The 24VAC, 2.0 VA actuators are available in a normally closed or normally open position, and with or without a valve position indicator.
