Schneider Electric (Barber Colman) MA-5213-500 Hydraulic Actuator

The Schneider Electric (Barber Colman) MA-5213-500 is an industrial-grade 24V two-position hydraulic actuator engineered for precise on/off control of dampers and globe valves in demanding HVACR environments. Built with a rugged die-cast lower housing and a painted steel upper enclosure, this unit utilizes an oil-immersed motor and pump to ensure smooth, consistent operation even in high-duty cycle applications. The spring return hydraulic actuator provides a critical fail-safe function, ensuring the system returns to its normal position within 15 seconds during a power interruption.

This model features a factory-installed SPDT auxiliary switch, allowing for seamless integration of end-of-stroke signaling or interlocking with auxiliary equipment. With a power consumption of 14 Watts and an 18VA input, the MA-5213-500 is optimized for energy efficiency while delivering an 11-pound linear force suitable for Schneider Electric VB-7000 series valves and various damper linkages. Designed for internal mounting with a NEMA 1 enclosure rating, it supports hardwired electrical connections via a 1/2-inch conduit opening, making it a reliable drop-in replacement for aging Barber Colman assemblies.

• Fail-Safe Reliability: Heavy-duty spring return mechanism ensures positive closure or opening upon loss of 24V power.
• Enhanced Control Logic: Integrated adjustable SPDT auxiliary switch facilitates easy system status monitoring without additional external relays.
• High Torque/Force Output: Specifically calibrated for linear movement to drive dampers and globe valves effectively.
• Durable Construction: Hydraulic oil-immersed design minimizes internal wear and extends service life in mechanical rooms.
• Wide Compatibility: Standard 24 VAC operation makes it compatible with most Building Automation Systems (BAS) and legacy control circuits.

Is the auxiliary switch on the MA-5213-500 adjustable?
Yes, the internal SPDT switch is adjustable and is typically factory-set to indicate when the actuator is at the retracted end of its stroke.

Can this actuator be used for both valves and dampers?
This model is versatile; it is designed for globe valves like the VB-7000 series and can be adapted for damper control using the appropriate AM-601 linkage kits.

What is the typical stroke speed for this unit?
The actuator typically extends the stroke in approximately 60 seconds under power and provides a quick 15-second spring return for safety positioning.
