1. The adjustable range is large, the inherent adjustable ratio is 50, and the flow characteristics are linear and equal percentage.

2. The valve body is designed according to the principle of hydromechanics, and the rated flow coefficient is increased by 30%.

3. The regulating and cutting type adopts the valve core with soft sealing structure, reaching the Class VI leakage standard (zero leakage).

4. The servo amplifier adopts depth dynamic negative feedback, which can improve the automatic adjustment accuracy.

5. There are many types of electric operators, which can be used for 4~20mA. DC or 0~10mA.DC.

6. The bellows sealed regulating valve forms a complete seal for the moving valve rod, blocking the fluid leakage.

7. The electronic electric control valve can directly control the valve opening by the current signal without servo amplifier.
