ball valve stainless 1

Stainless steel ball valve, also known as flange ball valve, is a self sealing structure. There is a raised flange on the bonnet and two matching grooves on the valve body. When it is closed, the flange on the bonnet faces up and the groove on the valve body faces down. Sealing surfaces are welded to prevent leakage and tearing. This stainless steel flanged ball valve is used for conveying liquids and gases. It is mainly used to open and close the fluid flow channel, and can also be used as an isolation device in the pressure system to cut off the flow.
