Rubber Disc Non-return valve is mainly composed of the three parts Body, Bonnet and Rubber disc.The disc is made of steel plate, steel rod & reinforced nylon cloth, and coated with N.B.R. outside.This disc has a service life on&off one million times. The full open flow channel minimizes water head loss and no room for deposit with easy maintenance.
This non-return valve is popularly used in water supply system. It is installed at outlet side of the pump to prevent backflow and water hammer damage at pump. It can also installed at bypass pipeline to stop water flowing back to the system.
Check valve, also known as one-way valve or check valve, is used to prevent the medium in the pipeline from flowing back. Check valves belong to the automatic valve category and are mainly used in pipelines with unidirectional flow of media, allowing only one direction of media flow. This type of valve should generally be installed horizontally in pipelines.
