Product Features:
·V type ball valve are fixed and single seat sealing ball valves.
·Its regulation performance is the best in ball valve. Flow characteristic is equal percentage, with adjustable ratio of 100:1.
·There is shearing action between v-shaped incision and metal seat. It’s especially suitable for fiber, tiny solid particles and slurry medium.
·V type ball valve regulating performance is good, used as a regulator.
·Using BSQ series ON-OFF electric actuator, with large output torque, simple operation, economical and practical, but shoudl avoid frequent operation.
