Performance:
Globe Control valve is composed of the pneumatic multi-springs, pneumatic actuator and the low flow resistance sleeve. This 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-regulating valve, it has low noise, simple structure and convenient assembling and dismantling characteristics.
The 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. It is suitable for the common fluid medium and techniques condition industrial control system.
?
Application:
The control valve has a wide range of control from vacuum valve to high pressure valve, from low temperature to high temperature. It is widely used in the automatic control process of petroleum refining, petrochemical industry, chemical fertilizer, general chemistry, steel, metallurgy, papermaking, electric power, light industry etc.
