ZSRO pneumatic control ball valve is a right angle rotary control valve, which is used in conjunction with an O-ring ball valve, pneumatic actuator, and valve positioner. It can achieve proportional adjustment, has precise flow characteristics and control functions, and is suitable for various control occasions. It has the advantages of large rated flow coefficient, large adjustable proportion, superior sealing performance, compact structure, small volume, etc. It is widely used in industries such as petroleum, chemical, power, papermaking, metallurgy, etc.
