Honeywell VP513A1048 3/4 Inch 7/8 Od,Flare2.5Cv,3-10Psi

The Honeywell VP513A1048 is a pressure regulator valve used in HVAC equipment to regulate the pressure of gases or liquids moving through pipes or tubes. Its diameters are 3/4 inch at one end and 7/8 inch at the other. Its adaptable controls allow it to manage pressure from 3 to 10 pounds per inch of space. The diaphragm and spring mechanism of the valve is how it operates. The diaphragm presses against a spring to open a valve and let extra pressure out when the pressure inside the pipe rises over the predetermined value. Despite variations in the upstream pressure, this keeps the pressure downstream of the regulator constant.
