Flow Check Valve For Boiler


Different Types Of Valves Use in Boiler - Maintenance SkillGate valve is a sliding type of Boiler valve. In the gate valve the closure membrane is a metal gate. These gates slide down to close the valve. The flow area is equal to the area of the pipe in fully open condition which results in negligible pressure drop across the valve.Heating System Boiler Check Valves, Flow Control Valves, …The flow check valve will open automatically when the pump starts to circulate the water. When the room thermostat reaches the set temperature and the pump shuts off, the flow check will close immediately preventing gravity circulation or "ghost flow." "Ghost flow" is caused by hot water rising and cold water sinking. Hot water rises in the vertical supply PEX pipes and cold water sinks in the vertical return PEX pipes. In systems with multiple zones, "ghost flow" usually occurs if a flow check or zone valve is not installed. A minimum of 12 inches of space between the pump and flow check valve is required for proper operation. Installing a flow check valve can increase the restriction in the line. The flow check valve must be disassembled (sweat only) prior to installation, as to not damage the internal components. Flow check valves …
