72R5230 cable-controlled water valve is engineered to improve heater system performance by regulating coolant flow more precisely. Designed with 5/8″ hose connections, this inline valve includes an integrated flow restrictor that limits coolant flow to approximately 5–6 gallons per minute through the heater core.
By reducing excessive flow, the valve provides easier modulation, extended water valve life, and maximized heater core efficiency, helping protect heater components from erosion and temperature spikes. The pull-to-open cable operation allows reliable manual control, making this valve ideal for Red Dot HVAC unit R-5045 and similar applications.
Manufactured to OEM-grade standards and widely cross-referenced across the industry, this valve is well suited for both service replacement and HVAC system optimization.
