Flanged ball valves

Ball valve – is one of the types of valves, in which the bolt has a spherical shape with a through hole. Through this hole passes gas, water or other aggressive or benign environment. The ball valve is working in positions “open-closed”, it is at position “open” and passed through a hole Wednesday. Ball valves come in a variety of modifications, and their application depends on how the environment they work. Ball valves can be used not only on the pipelines, but also on the conveyor. Depending on the type of connection to the pipeline ball valves are threaded, flanged and weld. Especially popular are ball valves threaded and flanged ball valves. The main advantage enjoyed by a ball valve flanged, is the reliability and controllable of valves, such crane is used mainly in utilities and construction. Flanged ball valves as a regulation of the flow is not used, because the ball valve flanged applies to full-view, that is only blocks or lets flow. These valves should not be used for uncleaned liquids, which contain an admixture of solids – this can lead to leaks, as in this case, Chassis Crane exposed abrasion. Flanged ball valve is ill-suited as a locking element and for leisurely and viscous liquids. Operating pressure at which the working crane is 1,6-4,0 MPa and a maximum ambient temperature should not exceed 200 C. flanged ball valves can be made from the following: 20, 12GS, 09G2S. The design of ball valve flange consists of a body, sleeves with cap flanges in the grooves which are Teflon seals. PTFE seals are pressed against the tap. Connections and spindle sealed with Teflon rings. Flanged ball valve is opened by turning the handle at 90 S. Brass ball valves are well sealed, light weight and light design. Such valves are very reliable, have high shockproof and resistant to environmental influences. Ball valves use saves energy costs. Resistance to tap the flow of the course is very little that is its unquestionable advantage over the valves and valves.
