A pinch valve is a valve that uses flexible piping to control the flow of fluid. It is suitable for particles,slurry,dust,corrosive media and high viscosity liquids. The working principle is to use an external device to squeeze the elastic pipe to control fluid flow. The valve closes when squeezed and opens when released. The main components include valve body,elastic piping and operating device.It is suitable for particles,slurry,dust,corrosive media and high viscosity liquids,etc. It has the advantages of unobstructed flow,low maintenance cost, prevention of media,contamination, corrosion and abrasion resistance,adaptability,simple operation.

Vacuum ball valves: can be used under vacuum as well as under low pressure. Its working pressure is lower than the standard atmospheric pressure, forming a certain vacuum.Ordinary ball valve: beyond a certain pressure will affect its sealing performance, so it can not be used in high-pressure environment.Vacuum ball valve: mainly used in vacuum systems, such as vacuum pumps, vacuum pipelines, etc., to ensure the vacuum of the system.Ordinary ball valves: widely used in a variety of fluid pipelines, such as water, steam, various corrosive media.In addition, vacuum ball valve material selection needs to have anti-corrosion, wear-resistant, high temperature resistance and other characteristics. The material selection range of ordinary ball valves is relatively wide.
