Multi-function 3-in-1 check valve, check valve

Features:

First, with a valve, you can successfully complete three functions: 1, waterless hammer check valve 2, globe valve 3, balance valve. Second, when the pump stops rotating, the spring force closes the valve disc first, thus preventing water hammer. Third, by adjusting the opening, you can adjust the output of the pump. Four, equipped with indicators, you can use the eyes to confirm the opening of the valve. 5. The sealing gasket is made of nitrile rubber, so it will not leak at all and can absorb impulse. Six, the spring is made of stainless steel, because it has strong corrosion resistance. Seven, can save water equipment materials and costs, reduce the installation space. Eight, because the shape and structure are highly streamlined, the pressure drop is small. 9, because it plays a side-channel role, it has the function of recycling the water in the outlet side pipeline, and when there is a vacuum on the inlet side, it adds water. 10, horizontal pipe, vertical pipe can be installed.

The three-in-one check valve is installed in the water supply and drainage of general buildings, apartments and factories, cold and warm water treatment, and the condensate of the boiler, and the pump outlet of the secondary water supply pipeline to prevent the medium backflow in the pipeline caused by the flash pump stopping operation.
