H43 Automotive Check Valve Series
H43 Automotive Check Valve Series
Application: Transportation
The Ranco H43 Series Check Valve Series is designed for automotive coolant systems. It limits or stops fluid flow in vehicles, tractors, and off-road equipment and reduces system noise by dampening pulsations in glycol-based coolants. The H43 valve is available in two versions:
H43-1000: Limits flow in flow restriction applications, protecting components from high pressure and flow erosion (e.g., heater cores).
H43-5000: Stops flow in check valve applications, preventing backflow in parallel loop systems (e.g., front/rear units, multiple heat exchangers in EVs).
Features and Benefits:
- Versions available for flow restriction and check valve applications
- Minimal pressure drop in full flow applications
- Port sizes available: 5/8″ and 3/4”
- Under the hood compatible up to 185°F (85°C)
