The V-type regulating ball valve has a special shape of fixed V-notch ball and adjustable metal seat structure. When the valve is closed, the V-shaped notch and the valve seat form a wedge-shaped shear effect, which can prevent the blockage of the dirt between the ball and the valve seat. It has the self-cleaning function, especially suitable for the medium containing fiber slurry, sewage and viscous particles. The valve positioner can realize continuous adjustment And the flow resistance is small, the adjustment range is wide, is a kind of widely used, high quality control valve.
Pneumatic V-regulating ball valve is a kind of high level control valve with right Angle rotary structure. It is used with valve positioner to realize proportional regulation. It can be used with two-position five-way solenoid valve and control box to realize switch control.Pneumatic V-ball valve spool is designed with special shape V-notch, with accurate closure property and control function, suitable for various control occasions, compact structure, small volume, can be installed in a tight position and other advantages.Pneumatic V regulating ball valve is suitable for gas, liquid, solid particle medium control. Because there is no gap between the valve core and the seat rotation, so it has a great shear force and self-cleaning performance, especially suitable for containing fiber or small solid particles of suspension and solid particles control. Therefore, the pneumatic V-ball valve products can be widely used in petroleum, chemical, paper, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial sectors of the automatic control system.
