SEVICON pneumatic regulating ball valve description
Pneumatic regulating ball valve is a right-angle rotary regulating valve, which can reach proportional regulation by using valve positioner, and can achieve on/off control by using two-position five-way solenoid valve and control box.
The advantages of pneumatic regulating ball valves are large rated flow coefficient, large adjustable ratio, superior sealing performance, compact structure, small volume and can be mounted vertically and horizontally. It’s suitable for controlling the gases, liquids and solid granular medium. As there’s no gap spinning between the spool and the base, it has excellent gear force and self-cleaning performance, especially suitable for controlling the suspensions liquid containing fibre or tiny solid particles. It’s widely used in petrol, chemical, electrical, pulping and metallurgy.
