Abstract

The article deals with the evaluation of the functional surfaces of the ball valve body, which are different from other parts of the ball valve. First is the requirement of decreased roughness of the machined surface of the catch surfaces and areas where it will be used a special sealing element, and also in dimensional tolerances and, ultimately, the position tolerances as coaxiality, parallelism and perpendicularity.

Keywords: Surface Roughness, Position Tolerances; Machining; Ball Valve
