York 024-39397-001 Flow Switch Freon Critical for accurate heat anticipationThe 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
