How Is The Piece Ball Valve Made So Perfect?

Piece Ball Valve comprises a bonnet that forms a closed structure with the valve body seat. The bonnet is equipped with a valve stem, one end of which is provided with a first drive pin, which is attached to a first drive plate. A support shaft is provided at the bottom end of the valve body seat, which is provided with a second drive pin, which is attached to a second drive plate. A ball is positioned between the first and second drive plates. This product features a simple structure, low manufacturing cost, fast opening and closing speeds, minimal wear, and easy operation.

This hard-seal ball valve and its production process are suitable for high-wear and highly corrosive operating conditions and address the brittle cracking issues of ceramic ball valves. This ball valve features a ceramic layer plasma-sprayed on the mating surfaces of the ball and seat. Leveraging the wear-resistant and corrosion-resistant properties of ceramic, it offers excellent internal sealing performance and a long service life in harsh operating conditions such as high wear, corrosion, high temperature, and high pressure. Furthermore, because the valve seat, ball, and valve body are still made of metal, brittle cracking of the valve seat and ball is avoided. When processing the ball and valve seat, this process coats a certain thickness of ceramic material on the mating surfaces of the ball and the valve seat to form a ceramic layer, then grinds the mating surfaces of the ball and the valve seat separately, and finally assembles the ball and the valve seat and grinds them to make the ball and the valve seat hard-sealed, so that the ball and the valve seat can achieve the matching accuracy required for hard sealing, thereby improving the sealing performance of the hard-sealed ball valve.
