York 024-39397-001 Flow Switch

The York 024-39397-001 Flow Switch is a mission-critical differential water pressure (DWP) control designed for high-performance HVAC and chiller systems. Engineered as a 24V flow switch, this component monitors real-time fluid movement to protect downstream equipment from dry-run conditions, pump cavitation, and thermal overload. Rated for a 150# DWP (150 PSI) maximum operating pressure, it provides the robust durability required for industrial and commercial hydronic loops. As a genuine York OEM replacement, this unit ensures seamless integration into existing control circuits without the need for field modifications. It is the designated direct replacement for York 024-26116-000 and 024-26116-100, correcting legacy failure points with improved sensing accuracy. For contractors managing York chiller maintenance or cooling tower operations, installing this factory-spec HVAC water flow sensor is essential for maintaining system balancing and preventing catastrophic compressor or coil damage. Its brass or stainless steel construction stands up to harsh mechanical room environments while delivering precise electrical signaling at 24V DC/AC thresholds.

• OEM Compatibility: Specifically engineered as a drop-in direct replacement for 024-26116-000 and 024-26116-100 legacy models.
• High Pressure Rating: Handles up to 150 PSI (150# DWP), making it suitable for high-rise commercial loops and demanding chiller applications.
• System Protection: Actively prevents pump cavitation and coil freezing by ensuring flow is established before high-voltage equipment engages.
• Low Voltage Integration: Optimized for 24V control circuits, allowing for straightforward wiring with standard HVAC controllers.
• Durable Construction: Built to withstand the constant pressure fluctuations and chemical additives found in closed-loop hydronic systems.
