Introduction：

The Hiton VQ series Worm Gear V notch Ball Valve is primarily designed for flow control, and it can also be used for shut-off

operation. The notched port on the segment ball contributes to strong shear stress to cut through media with fibers

and particles. Consequently, this Segment Ball Valve is a good general control valve (equal percentage flow character) 

for most pulp and paper process applications, or similar flow contains fibers and particles.

 

Features:

1.    Body：

a)     Integral body design offers greater rigidity against fluctuating pipe loads.

b)     Eliminates the leak path associated with two piece body designs.

c)      Both wafer and flange connection are available.

 

2.    Core：

a)     Specially designed V-notch ball provides strong cutting stress and tight sealing. 

b)     Hard chromium, nitriding, and HCOF treatments are all available for the ball surface treatment, improving hardness, 

        abrasion resistance, fatigue resistance, corrosion resistance and performance under high temperature.

c)     Well ground notched ball surface ensures small operating torque and tight seal, especially for metal seated

        segment valve.

3.    Seat：

a)     For valve rated under class 150, retainer is casted on valve body to eliminate any possible space between seat 

        ring and body for residue accumulation. Consequently, this ensures perfect seal。

b)     Specialized spring design decreases valve torque while providing force for tight sealing. 

c)     Pressure energized seat design offers excellent sealing even at very low differential pressures.

4.    Stem：

a)      The stem is finely ground to match the actuator excellently, which prevents rocking motion and potential failure 

         of the segmented valve.
