ER-G03, ER-G06 electric-hydraulic proportional pilot valve

Pilot valves ER-G03, ER-G06 are auxiliary valves used to operate control mechanisms in other valves or components.

  

Common features of pilot valves

 

1) form the pilot control liquid bridge with the fixed liquid resistance, and control the main valve or the secondary valve or the variable bar according to the input signal;

 

2) the flow rate of the head pilot valve is generally only about 1 l/min, with a maximum of 3 l/min. The flow rate of the secondary pilot valve shall be determined according to actual needs.

 

3) the input signals are relatively small;

 

4) can accept a variety of input methods, such as manual, electric, hydraulic, pneumatic, mechanical CAM, electric proportion, etc.;

 

5) in the case of variable pump control, a variety of pilot valves form a modular structure, a variety of functions to facilitate choice;

 

6) pilot valve itself is often a small size control valve, mostly pressure control valve.
