SPV Pneumatic V-notch Ball Control Valve

SPV Pneumatic V-notch Ball Control Valve

SPV Pneumatic V-notch Ball Control Valve


SPV pneumactic v-notch ball control valve is composed of  GTX-B series pneumatic rack and pinion actuators and v-notch control ball valve body assembly. Its V-shape notch segmented ball permits wide rangeability and produces an equal percentage flow characteristic. As the V-notch ball rotates into the seat ring, it creates a wedging and shearing effect to prevent dragging or slurries between the seat and the ball. Therefore, especially suitable to large rangeability service and /or control of fluids with fiber and/or slurry.

SPV pneumactic v-notch ball control valve is characterized by compact structure, effective operation and long lifetime. It can be widely used in oil, chemical, power station, paper and pulp, metallurgy, sewage treatment etc. processing industries to control high pressure or high pressure drop fluid, especially suitable for the fluid entrained with fiber or particle.
