Wai Hang Sanitary Internal Thread Check Valve
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.
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 valve open when the pressure of the fluid exceeds the pressure to spring, when the two pressure are equalised,the valve close. A stronger counter pressure also makes the valve close.
