Three in one check valve

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

三合一止回阀feature
1. With one valve, three functions can be successfully completed: water hammer check valve, gate valve, and balance valve.
2. When the pump stops running, the spring force closes the valve disc first, thus preventing water hammer.
3. By adjusting the opening, the output of the pump can be adjusted.
4. Equipped with an indicator, it can visually confirm the opening degree of the valve.
5. The sealing gasket is made of nitrile rubber, so it will not leak at all and can absorb impact.
6. The spring is made of stainless steel and therefore has strong corrosion resistance.
7. Three functions can save equipment materials and costs, and reduce installation space.
8. Due to its streamlined shape and structure, the pressure drop is very small.
9. Both horizontal and vertical pipelines can be installed.
