Pneumatic pressure modulating control valve is composed of the pneumatic multi-springs, pneumatic actuator and the low flow resistance sleeve. Pneumatic pressure modulating control valve uses the balanced valve core, the unbalanced force is small, the permission pressure differential is big, and operation is steady. Compared with the ordinary single and double seat control valve, it has low noise, simple structure and convenient assembling and dismantling characteristics.
         Pneumatic pressure modulating control valve shape is small, the body is light, the performance is good, and the capacity is big. So it's the new type general regulating valve product. Pneumatic pressure modulating control valve is suitable for the common fluid medium and techniques condition industrial control system.
