Product Overview:

Our slow-opening and slow-closing multi-function check valve is designed and manufactured with reference to advanced imported products and domestic counterparts.
It is primarily installed on the pump outlet pipelines of high-rise building water supply systems and other water supply systems to prevent medium backflow and to prevent water hammer and surge phenomena.This single valve combines the functions of an electric valve,a check valve,and a water hammer eliminator,effectively improving the safety and reliability of the water system.


Product Features:

1.Excellent water hammer elimination.The technical principles of slow-opening and slow-closing are integrated to prevent water hammer during pump startup.
2.Easy operation.Simply operate the pump motor start/stop button,and the valve will automatically open and close in accordance with pump operating procedures.
3.Energy efficient.The valve features a wide valve body,full-bore streamlined straight-through design,resulting in low pressure loss,large flow capacity,as well as compact size and light weight.
4.Adjustable opening pressure.Equipped with a pilot valve control system,the main valve opening pressure can be set simply by adjusting the pilot valve,and the opening pressure can be flexibly adjusted according to operating conditions.
