PRODUCT OVERVIEW
The pipeline pneumatic shuttle valve is mainly used as the terminal control component in the fluid transmission process control system of nitrogen making equipment, oxygen making equipment and other equipment in the air separation industry. The valve is a right angle rotary structure, which can be used together with the valve positioner to realize proportional adjustment; V-shaped valve core is suitable for various regulating occasions. It has large rated flow coefficient, large adjustable ratio, good sealing effect, zero sensitivity of regulation performance, small volume and can be installed vertically and horizontally. Suitable for controlling gas, steam, liquid and other media. It has the characteristics of simple structure, small volume and large flow. It is widely used in the control system of fluid transportation process in petroleum, chemical industry, metallurgy, light industry, medicine, electric power and other industrial departments.
