Silent Check Valve
The silent check valve refers to the automatic opening and closing of the valve disc by means of the flow of the medium itself. This valve is used to prevent the medium from flowing backward, also known as reverse valve, one-way valve, counterflow valve. The valve is suitable for water supply and drainage systems and the pipeline network systems of the high-rise buildings, and is used in the pipeline of the pump outlet.
Features

- Long pilot shaft can effectively prevent the valve disc displacement; the cable that goes through can be placed at the unique flange cut-outs (DN100 and below)
