As a veteran-grade \u003cstrong\u003ehumidifier solenoid valve\u003c\/strong\u003e, this assembly features a 24V DC electronically controlled actuator integrated with a \u003cstrong\u003e0.5 GPM flow regulator\u003c\/strong\u003e and a built-in strainer. Constructed from durable aluminum to withstand the high-cycle demands of \u003cstrong\u003ecomputer room air conditioning (CRAC)\u003c\/strong\u003e systems, it ensures efficient condensate removal and prevents mineral buildup that can compromise humidifier pan performance. This \u003cstrong\u003eHVAC solenoid valve assembly\u003c\/strong\u003e is engineered for a secure fit with \u003cstrong\u003eNPT threaded connections\u003c\/strong\u003e, effectively replacing legacy part numbers P-5590, P-5590S, and 185398G1. Utilizing an \u003cstrong\u003eautoflush solenoid\u003c\/strong\u003e maintains system hygiene by purging stagnant water, which is a critical preventative measure against scale and corrosion in high-sensitivity data center applications. For technicians managing Liebert infrastructure, this \u003cstrong\u003e0.5 GPM solenoid valve\u003c\/strong\u003e provides the exact flow rate required to match factory specifications for optimal water management and system longevity.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecise Flow Control:\u003c\/strong\u003e The \u003cstrong\u003e0.5 GPM regulator\u003c\/strong\u003e ensures the correct volume of water during flush cycles to prevent overflow or insufficient purging.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated Filtration:\u003c\/strong\u003e A built-in \u003cstrong\u003esolenoid valve strainer\u003c\/strong\u003e captures particulates before they reach the valve seat, preventing clogs and internal leaks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect OEM Compatibility:\u003c\/strong\u003e Engineered as a drop-in replacement for \u003cstrong\u003eLiebert 185108P1S\u003c\/strong\u003e, eliminating the need for field modifications or bracket adjustments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRobust Construction:\u003c\/strong\u003e Lightweight yet rugged aluminum housing handles 60Hz electrical environments and high-frequency switching.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the primary function of the AutoFlush valve in a Liebert unit?\u003c\/strong\u003e\u003cbr\u003e\nThe \u003cstrong\u003eAutoFlush solenoid valve\u003c\/strong\u003e periodically drains the humidifier water pan to remove concentrated minerals and sediment, ensuring the infrared or steam canisters operate at peak efficiency.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan the 185108P1S replace a standard water solenoid?\u003c\/strong\u003e\u003cbr\u003e\nWhile it is a solenoid valve, this assembly is specific to the flush side of the humidifier system and includes a calibrated \u003cstrong\u003e0.5 GPM flow regulator\u003c\/strong\u003e. It should only be used in applications matching these technical specifications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this valve compatible with 120V systems?\u003c\/strong\u003e\u003cbr\u003e\nNo, the \u003cstrong\u003eLiebert 185108P1S\u003c\/strong\u003e is designed for 24V DC control circuits. Wiring this component to a 120V or 240V source will result in immediate coil failure.\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.
