BGTQ Pneumatic V Port Ball Valve
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.
·With BGT angular travel series pneumatic actuators, it can control a small V type ball valve.
·The pneumatic actuator must be with positioner to modulate the opening degree of valve.
