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.
·Ball valve rotate 90 ° to complete fully open/close fast. Low friction coefficient and small operating torque .
·Valve good sealing, a variety of the seat material, wide adaptation.
·Worm gear operation, large output torque. It can control a large ball valve.
·There is shearing action between v-shaped incision and metal seat. It’s especially suitable for fiber, tiny solid particles and slurry medium.
