PVC compact ball valve is evolved from the cock, its opening and closing parts for a ball, through the stem rotation 90 degrees to achieve the valve switch, PVC compact ball valve in the pipeline is mainly used to cut off, distribution and change the flow of media, designed into a V-shaped opening PVC compact ball valve also has good flow regulation performance. PVC compact ball valve quickly open and close, good sealing, simple structure, low flow resistance, widely used in modern industrial occasions.


PVC compact ball valve


PVC compact ball valve according to the structure can be divided into fixed PVC compact ball valve, floating PVC compact ball valve, track PVC compact ball valve, V-shaped PVC compact ball valve, eccentric semi-PVC compact ball valve, three-way PVC compact ball valve, four-way PVC compact ball valve; According to the connection mode, it is divided into flange PVC compact ball valve, clamping PVC compact ball valve, internal thread PVC compact ball valve, external thread PVC compact ball valve, welding PVC compact ball valve, clamp PVC compact ball valve (generally sanitary grade PVC compact ball valve), sleeve TYPE PVC compact ball valve, etc. According to the sealing material can be divided into soft sealing PVC compact ball valve and metal hard sealing PVC compact ball valve. Soft sealing PVC compact ball valve is generally suitable for the temperature is less than 150 degrees or so of the medium, more than 150 degrees of the medium, then choose PPL seal or metal seal.


Small diameter PVC compact ball valve, generally with floating PVC compact ball valve, large diameter PVC compact ball valve, because the need for opening and closing torque is relatively large, often choose fixed PVC compact ball valve, can reduce the torque required when opening and closing, improve the reliability of the work. V-type PVC compact ball valve and eccentric half PVC compact ball valve, can be used to adjust the flow, three-way PVC compact ball valve and four-way PVC compact ball valve are used to reverse the fluid.


PVC compact ball valves are commonly used in carbon steel, 304 stainless steel, 316 stainless steel, for highly corrosive medium, the valve body and ball lined with ptfe. PVC compact ball valve drive mode is mainly electric, pneumatic, worm gear transmission, small caliber manual PVC compact ball valve, are generally used to open and close the handle.
