Product Description
Wai Hang Sanitary Check Valve
A check valve, also known as a non-return valve, one-way valve, reflux valve or isolation valve, is a valve with a round opening and closing part (valve flap) that blocks the backflow of the medium by its own weight and medium pressure. Its main function is to allow the fluid to flow in one direction only. When the fluid flows back, the valve flap will automatically close, thereby cutting off the flow path and preventing damage caused by backflow.
Application Fields
Check valve is for prevents the fluid from flowing back and ensures to flow in only one direction. It can be used to prevent the flow less from returning avoid pipe hammering. It is widely used in the food processing, beverage,wine,oil,cosmetics,pharmaceutical and chemical industries.
Operation Principles
The working principle of the check valve is to realize automatic opening and closing by relying on the weight of the opening and closing parts (valve disc) and the medium pressure. When the medium flows in from the inlet end, the valve disc is pushed open by the medium pressure, and the medium can flow; when the medium flows back, the valve disc is closed by the dual action of its own weight and the backflow medium pressure, preventing the medium from flowing back.
There are various standard valve series can be supplied, they are the DIN,3A, SMS, ISO/IDF, BS/RJT, ASME/BPE standard etc. You can choose us with confidence, our products meet the standards of multiple regions, such as American Standards, Japanese Industrial Standard, Korean Standard, German Standard and Italian Standard. The constitute elements of ball valve always included: one handle, one ball body with transfixion cavity, valve body, valve central spindle and spindle shaft seal.

Check valve refers to a valve whose opening and closing part is a round valve disc and acts by its own weight and medium pressure to block the backflow of the medium. The combination of the check valve and the globe valve can play a role in safety isolation. The opening and closing parts are automatically opened or closed by the force of the medium flow to prevent the backflow of the medium called the check valve. The check valve belongs to the automatic valve class, which is mainly used on the pipeline with one-way flow of the medium, and only allows the medium to flow in one direction to prevent accidents.
