Description
The AERCO 89030 is a precision-engineered cartridge globe valve actuator designed for reliable modulating control in commercial HVAC and hydronic systems. Accepting a 0/2–10 VDC control signal with a 100K ohm input impedance, this actuator integrates seamlessly with building automation and direct digital control systems. Its 24VAC power supply requirement and low 5 VA power consumption make it an energy-efficient choice for a wide range of valve control applications.

- Humidity range: 5–95% RH (non-condensing)
Reliable Fail-Safe Operation
The spring return mechanism ensures the valve stem returns to the up (open or closed, depending on valve configuration) position within 10 seconds in the event of a power loss, providing dependable fail-safe protection for your hydronic or chilled water system.
Modulating Control Precision
With a 0/2–10 VDC input range and high 100K ohm input impedance, the AERCO 89030 delivers accurate, proportional flow control, minimizing hunting and maximizing system efficiency. The 90 lbf stem force ensures positive valve seating even under elevated system pressures.
Broad Environmental Compatibility
Rated for ambient temperatures from 32°F to 122°F and relative humidity from 5% to 95% RH, this actuator is built to perform reliably across a wide range of mechanical room and field installation environments.
