V type slurry control ball valve owns a V-notch cut plug to product wedge-shaped shearing action between the V-notch cut and seat when the valve closed, and to realize the function of self-cleaning and prevent the blockade phenomenon caused by the dirt between plug and seat. The valve is suitable for not only the common liquid, but also the medium of control system, swage, fibrous and small solid particles.
V type slurry control ball valve is matched with pneumatic or electric actuator together to compose the auto-control pneumatic control valve or electric control valve, which easily meets various auto-control requirements for flow, temperature, pressure in the industrial auto-control system including electric power, petroleum, metallurgy, and papermaking.
Valves are full port, so they do not restrict flow. The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.

Single-acting(spring return) actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied to close them, so they do not have a valve starting position.
