This \u003cstrong\u003e24V AC\u003c\/strong\u003e component operates with a \u003cstrong\u003e2k ohm\u003c\/strong\u003e position feedback potentiometer, ensuring localized accuracy for floating point control signals. Designed as a non-spring return \u003cstrong\u003emod motor\u003c\/strong\u003e, it delivers a robust \u003cstrong\u003e225 in-lb torque\u003c\/strong\u003e (often rated at 90# or 225# depending on the valve assembly) to manage flow rates of water or steam within \u003cstrong\u003eVertiv\u003c\/strong\u003e and Liebert precision cooling units. This model is the verified direct replacement for the legacy \u003cstrong\u003eJohnson Controls VA-7203-5001\u003c\/strong\u003e and the \u003cstrong\u003eLiebert 146351P1S\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Compatibility:\u003c\/strong\u003e Specifically designed for Liebert precision cooling systems, eliminating the need for complex field wiring modifications required by universal alternatives.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnetic Clutch Protection:\u003c\/strong\u003e Features an integrated magnetic clutch that provides constant output force for positive valve close-off and protects internal gears during stall conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Accuracy Feedback:\u003c\/strong\u003e The \u003cstrong\u003e2k ohm\u003c\/strong\u003e feedback potentiometer allows the controller to monitor the exact valve position, optimizing thermal stability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Seamlessly replaces \u003cstrong\u003e146351P1S\u003c\/strong\u003e and \u003cstrong\u003eVA-7203-5001\u003c\/strong\u003e models, ensuring minimal downtime during emergency repairs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Liebert 10046890P1S a spring return actuator?\u003c\/strong\u003e\u003cbr\u003e\nNo, this is a \u003cstrong\u003enon-spring return\u003c\/strong\u003e actuator. It requires a 24V signal to drive the motor in both directions via floating point control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should I check if the actuator is clicking but not moving the valve?\u003c\/strong\u003e\u003cbr\u003e\nCheck for \u003cstrong\u003evalve binding\u003c\/strong\u003e or debris in the globe valve body. If the valve moves freely manually, the internal gears or the magnetic clutch of the \u003cstrong\u003e10046890P1S\u003c\/strong\u003e may be compromised.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this to replace older ML984 series actuators?\u003c\/strong\u003e\u003cbr\u003e\nYes, but you will likely need the 149111P1S adaptor kit to ensure proper mechanical alignment and stroke distance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
