Product name：Stainless steel ball valve
Product category：Forged steel ball valve
Information
Forged steel ball valve works by rotating the stem to make the valve unblocked or blocked. Can full bore ball valve, 90 degree angle, valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries. Forged steel ball classification: low pressure forged steel ball valve, high pressure forged steel ball valve.
