Liebert 10046890P1S Actuator
The Liebert 10046890P1S Actuator is a high-precision electric globe valve actuator engineered specifically for critical climate control in data centers and industrial HVAC environments. This 24V AC component operates with a 2k ohm position feedback potentiometer, ensuring localized accuracy for floating point control signals. Designed as a non-spring return mod motor, it delivers a robust 225 in-lb torque (often rated at 90# or 225# depending on the valve assembly) to manage flow rates of water or steam within Vertiv and Liebert precision cooling units. This model is the verified direct replacement for the legacy Johnson Controls VA-7203-5001 and the Liebert 146351P1S, often requiring an adapter kit when substituting certain ML984 series units. Constructed with a NEMA 1 rated plastic housing and a magnetic clutch to prevent motor stall, it provides the exact fit and 0.75-inch stroke length necessary for maintaining tight tolerances in high-demand mechanical rooms.
Key Benefits- OEM Compatibility: Specifically designed for Liebert precision cooling systems, eliminating the need for complex field wiring modifications required by universal alternatives.
- Magnetic Clutch Protection: Features an integrated magnetic clutch that provides constant output force for positive valve close-off and protects internal gears during stall conditions.
- High-Accuracy Feedback: The 2k ohm feedback potentiometer allows the controller to monitor the exact valve position, optimizing thermal stability.
- Direct Replacement: Seamlessly replaces 146351P1S and VA-7203-5001 models, ensuring minimal downtime during emergency repairs.
Is the Liebert 10046890P1S a spring return actuator?
No, this is a non-spring return actuator. It requires a 24V signal to drive the motor in both directions via floating point control.
What should I check if the actuator is clicking but not moving the valve?
Check for valve binding or debris in the globe valve body. If the valve moves freely manually, the internal gears or the magnetic clutch of the 10046890P1S may be compromised.
Can I use this to replace older ML984 series actuators?
Yes, but you will likely need the 149111P1S adaptor kit to ensure proper mechanical alignment and stroke distance.
