Pneumatic flange regulating ball valve

The valve uses V type channel ball valve with ultra short ball and pneumatic actuator, the valve positioner, can achieve linear regulation of micro flow, is a wide range of new use of the new control valve. Pneumatic control valve is a right angle rotary valve with the valve positioner supporting the use of proportional control can be achieved, and supporting the use of the two position five way solenoid valve and control box can realize the switch control of.V type ball valve core design of V notch with a special shape, with closure properties and control function of sperm indeed, suitable for various control occasions, with a rated flow coefficient, adjustable ratio, excellent sealing performance, compact structure, small size, can be vertical horizontal installation and other advantages. For gas, liquid, solid granular media control. Because no gap between the spool and the valve seat is rotating, so have a lot of shear force and self-cleaning performance, particularly suitable to contain fibrous or suspension of small particles and solid particles. The products are widely used in petroleum, chemical, electric power, papermaking, metallurgy and other industries.
