Honeywell VP513B1053 Flare Valve 1/2" X 5/8" OD 2.5Cv 9-13 PSI

The Honeywell VP513B1053 Flare Valve is a pressure-regulating part that is used to regulate the flow of fluids in residential and light commercial level plumbing and HVAC systems. It has an outward connection of 1/2" by 5/8" and a flow coefficient of 2.5 Cv which keeps the system pressure within the range of 9-13 PSI, which makes all downstream components consistent in their operation. The valve is installed in piping circuits, where it is adjusted to change the flow depending on changes in the pressure to ensure the correct operation of appliances like boilers, water heaters, and heating units.
