York 024-39397-001 Flow Switch 30067439-890 Designed to regulate manifold pressure

Designed to regulate manifold pressure within a precise 3-5" WC range

it functions as a primary operator for the 240V load side

System Safety: Operates as a critical safeguard against equipment failure by managing temperature-controlled HVAC thresholds

While the internal bore may fit the same valve stem

mounting with the coil upright is recommended to prevent sediment buildup in the pilot orifice

York 024-39397-001 Flow Switch 30067439-890 Designed to regulate manifold pressureThe 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
