Description
Ball valves are one of the most modern and progressive types of valves. It is noteworthy that they can be varied in their design, material of production, installation method and field of application. They are united by the presence of a shut-off element, in most cases made in the form of a ball, allowing or blocking the working flow.
Generally, in the production of a ball valve, one of the main problems is the high labor intensity of obtaining the required quality of spherical plugs (ball spheres). The reliability of the valve is determined by such qualities of the ball as small deviations from the sphericity and the absence of microroughnesses. A high-quality ball (sphere) is an ideal mirror surface and accurate geometric parameters.
In our company, you can also purchase ball valves.
