Designed for use in any internal combustion coolant loop, Robertshaw’s motorized valve solutions are the top choice for OEMs around the world for both residential and commercial applications.
H38 Series
Application: Transportation
The Ranco® Solenoid Action Coolant Valve Series controls the secondary heating coil in vehicles with rear cabin HVAC systems. These are metal valves and applications include people movers, fire trucks, and ambulances. H38s are also available in Cable and Vaccum driven versions.
Features and Benefits:
- Valve driven by actuator
- Saves energy compared to traditional solenoid valve
- Does not require constant power to keep valve in closed position
- Valve drive to open position in case of energy loss
- Capacitor internal to actuator provides back-up power
- Minimal pressure drop in full flow applications
- Two terminal electrical interface on the actuator
- Integral mounting bracket
- Available in 2 and 3 port configuration
Specifications:
- Fluid: Ethylene Glycol
