The API pneumatic V-shaped regulating ball valve produced and sold by Huadian Pump Valve is an advanced control valve with right-angle rotary structure, which is used with the valve positioner to achieve proportional adjustment; Used with two-position five-way solenoid valve and control box, switch control can be realized. The pneumatic V-shaped ball valve spool is designed with a special shape V-shaped notch, with accurate shut-off and control functions, suitable for various control occasions, compact structure, small size, can be installed tightly and other advantages. Pneumatic V-type regulating ball valve is suitable for the control of gaseous, liquid and solid granular media. Due to the gapless rotation between the spool and the seat, it has great shear force and self-cleaning performance, especially suitable for the control of turbidity and solid particles containing fibrous or microscopic solid particles. Therefore, pneumatic V-shaped ball valve products can be widely used in petroleum, chemical, papermaking, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial departments of automatic control system.
