  • Heating System Boiler Check Valves, Flow Control Valves

    Some flow control valves act as a check valve, preventing fluid from drifting into places where it doesn't belong or zones that are not calling for heat. Additionally, a flow control valve prevents zones from overheating due to gravity circulation. Gravity circulation occurs during periods when the boiler is hot, but the heat is unwanted in a zone.Learn More
