Cast steel ball valve opening and closing pieces (ball) by the valve stem, and around the stem axis of rotation for the valve. Mainly used to cut off or connect the medium in the pipeline, can also be used for fluid regulation and control, in which the V-shaped ball valve hard seal its V-shaped core with hard metal welding seat metal seat has a strong shear Shear, especially for containing fibers, small solid particles and other media. Cast steel ball valve is generally divided into handle cast steel ball valve, pneumatic cast steel ball valve, electric cast steel ball valve, cast iron ball valve, stainless steel ball valve, copper ball valve.
Forged steel ball valve works by rotating the valve stem to make the valve clear or blocked. Full diameter ball valve can be 90 ° angle, ball valve switch light, small size, can be made of large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often closed state, not easy to be media erosion, in various industries Get a wide range of applications.
Forged steel ball valve is based on the needs of users, in order to meet the vulcanization applications in sulfide sulfide cracking requirements, this series of high-pressure forged steel ball from the design, material selection, manufacturing, testing, surface treatment and paint are strictly in accordance with the United States Corrosion Engineer NACE standards will be required.
