Pneumatic v-type ball valves are composed of pneumatic horizontal piston actuators (hereinafter referred to as pneumatic piston actuators) and v-type ball valves. It powered by compressed air, stem drive the ball in the valve body rotate 90 degrees, realization of full open to full close action, the v-shaped ball core has a shearing action between mouth and his seat, has the extremely good regulating and cut off performance, widely used in petroleum, chemical industry, papermaking, metallurgy, sewage treatment, oil tank truck etc, for all kinds of liquid, gas, slurry type fluid medium such as regulation and cut off the control, especially suitable for control of high viscosity, medium with fiber and fine particles.
