Eclipse 501202 1.25 Inch Npt 5Bv-A Valve

The Eclipse 501202 is a pressure-regulating butterfly valve, especially a 1.25-inch NPT 5Bv-A valve. It is essential to hydronic heating and cooling systems because it controls water flow, which keeps the system's pressure constant. Maintaining constant pressure is crucial for effective functioning and safeguards equipment from harm resulting from variations in pressure. A revolving disc that is positioned inside the flow stream is how the valve operates. This disk has a shaft attached to it that is adjusted by a spring. IS forced by increasing water pressure, which causes the disc to rotate and restrict the flow path, lowering pressure. On the other hand, the spring counteracts when the pressure decreases, opening the disc wider and increasing flow. The system's desired pressure is maintained by this automatic adjustment.
