The working principle of forged steel ball valve is to open or close the valve by rotating the valve stem. It is usually a full-bore ball valve with a 90-degree angle switch. It is light, small in size, can be made into a large diameter, has reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. It is widely used in various industries. Forged steel ball valve classification: low-pressure forged steel ball valve, high-pressure forged steel ball valve.
