| TWA actuators are used to electically activate valves on hot water heating systems, where slow opening and closing is desirable to eliminate water hammer associated with quick acting valves. TWA is a low voltage (24V), low power consumption actuator equipped with a visual indicator to show the open or closed position of the valve. TWA actuators can be selected to create either a normally open or a normally closed control. Maximum ambient temperature is 140F (60C). |
