SEV Electric Control Ball Valve
SEV Electric control ball valve is composed of 3601R series angular travel electronic electric
actuators and control ball valve body assembly. Its V-shape notch segmented ball permits wide
range ability and produces an equal percentage flow characteristics. 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 range ability service and /or control of fluids with
fiber and/or slurry.
SPV pneumatic v-notch ball control valve is characterized by compact structure, effective handle 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.
