ASCO AH2E212S4 Actuator

The ASCO AH2E212S4 Actuator is a high-performance electrohydraulic linear actuator designed for the reliable control of V710 gas valves in industrial and commercial combustion systems. Operating on a 120Vac power supply, this Hydramotor features a fast opening construction, achieving full stroke in as little as 14 seconds. Engineered for safety and precision, the unit includes an integrated Proof of Closure switch (SPDT) to provide a remote electrical signal when the valve is in the fully closed position, ensuring compliance with rigorous system interlock requirements. Built with a Type 1 general purpose enclosure, the ASCO AH2E212S4 is optimized for indoor environments such as boilers, furnaces, and ovens. This on-off actuator is supplied with a damper shaft and arm, allowing for simultaneous modulation of air dampers and gas flow. Its push-type, self-contained design ensures a rapid spring return shutoff of one second or less upon power interruption, providing critical protection for main line gas control applications.

Common Questions

Can the ASCO AH2E212S4 be used outdoors?
No, this model features a Type 1 Enclosure, which is rated for general purpose indoor use. For outdoor applications or wash-down areas, a watertight enclosure variant is required.

What valves are compatible with this Hydramotor?
The AH2E212S4 actuator is specifically designed to mount directly to ASCO V710 series gas valve bodies using three set screws.

Does this unit support 50Hz operation?
Yes, it is rated for 110Vac/50Hz as well as 120Vac/60Hz. Note that opening times may increase by approximately 20% when operating on a 50Hz frequency.
