• V-ball valves are suitable for various pipelines from Class 150 to Class 300 and PN16 to PN40. Depending on the user's requirements, V-ball valves have two different uses: one is as a shut-off valve to cut off or connect the medium in the pipeline, and the other is as a regulating valve to adjust the flow rate and other parameters of the medium in the pipeline. The driving mode of the cut-off V-shaped ball valve is manual, worm gear transmission, pneumatic or electric, while the driving mode of the regulating V-shaped ball valve is pneumatic and electric. By selecting different Material, V-ball valves can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media. The operating temperature of metal hard sealed V-shaped ball valves is generally ≤ 200 ℃. For special orders, the operating temperature of metal hard sealed V-shaped ball valves is ≤ 425 ℃ (carbon steel valve body) or ≤ 540 ℃ (stainless steel, chromium molybdenum steel, chromium molybdenum vanadium steel valve body), and the operating temperature of soft sealed V-shaped ball valves is generally ≤ 180 ℃ (reinforced polytetrafluoroethylene valve seat). The connection method for V-shaped ball valves is either clamp connection or flange connection.

Features

1. The V-shaped ball valve adopts a movable valve seat structure loaded with disc springs or cylindrical springs, and the valve seat and V-shaped ball will not get stuck or detached, with reliable sealing and long service life.

2. There is a shear effect between the V-shaped cut ball and the metal valve seat, which is particularly suitable for media containing fibers, solid particles, slurry, etc.

3、 The sealing surface of the metal hard sealed sphere and valve seat can adopt various advanced processes such as spray welding nickel based alloy (hardness ≥ HRC60), supersonic spray tungsten cobalt alloy (maximum hardness ≥ HRC70), and special hardening materials according to different user operating conditions, which are suitable for various harsh working conditions.

4、 When the valve is fully opened, the flow capacity of the valve is large, the Pressure loss is small, and the medium will not be deposited in the valve body cavity.

5、 Compact structure and strong universality. The cut-off V-shaped ball valve has good sealing performance and can replace various valves such as gate valves, globe valves, and ordinary ball valves. The adjustable V-shaped ball valve has a large adjustable range and high adjustment accuracy.
