VALSTEAM ADCA AVM234S - AVF234S ACTUATORS

The AVM234S / AVF234S valve actuators offer automatic adaptation to the stroke of the valve, precision activation and high energy efficiency with minimal operating noise. Ideal for use with any DSH series direct steam injection humidifier and in TDS (Total Dissolved Solids) control systems VCP blowdown valves. In case of power failure/interruption, the AVF234S actuator runs, spring-driven, into its respective fail-safe position (thrust rod extended). In modulating duty, the end position seating is made via limit switches.
