72R5280 is a cable-controlled heater water valve designed for applications requiring precise coolant flow control. This inline valve uses 5/8 in. hose connections on both the inlet and outlet and operates in a pull-to-open configuration.
An integrated flow restrictor reduces coolant flow to approximately 5–6 gallons per minute, allowing smoother temperature modulation, extending water valve service life, and maximizing heater core efficiency. This valve is well suited for HVAC systems where controlled heat output and long-term reliability are critical.
