Control valve
ZSRF pneumatic piston eccentric rotary control valve is a high-performance control valve that combines an eccentric rotary valve core and a pneumatic piston actuator. It is designed for high-precision flow control and harsh working conditions. Its unique eccentric rotary structure takes into account the characteristics of high regulation accuracy, good sealing, and strong anti-scouring ability. It is widely used in fluid control systems in the petroleum, chemical, electric power, metallurgy and other industries.
Manufacturing Range
Valve body material: carbon steel, stainless steel, alloy steel
Nominal diameter: DN25 ~ DN600
Pressure range: PN16 ~ PN160
Connection: flange, clamp, welding

Design Features
Intelligent positioning and feedback:
Optional intelligent positioner (such as HART/Foundation Fieldbus) supports 4-20 mA signal feedback and remote diagnosis.
Fire safety design:
Complies with API 607/6FA fire protection standards, and the metal seal can still maintain emergency cutoff after the soft seal fails.
Explosion-proof certification:
The actuator is ATEX/IECEx certified and suitable for explosive environments (such as oil and gas fields, chemical plants).
