The bellows globe valve can reach the zero leakage standard of helium mass spectrometry detection, which is very safe and reliable.

Before installing the valve, the user must check the valve model, connection size and pay attention to the flow direction of the medium to ensure consistency with the valve requirements.

It relies on the pressure of flowing medium in the pipeline to push the valve disc to close and open the valve. When the medium stops flowing, the check valve disc will close. It can effectively prevent the medium in the pipeline from backflow.

Knife gate valve is suitable for various powder and slurry fluids in the general petrochemical and other food industries, cement and paper making, environmental protection and other industries.

The valve that opens or closes on its own by the force of the flow of the medium to prevent the medium from flowing back is called a check valve. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the me......

Many industries require more and more valves. If double eccentric butterfly valve are required to withstand high temperature, hard seal must be used, but the leakage of hard seal butterfly valves is large; If the valve is required to leak zero, the valve must be soft sealed, but the soft seal butter......
