What are the product characteristics of the pilot valve

Pilot valves are auxiliary valves used to operate control mechanisms in other valves or components.

What are the characteristics of the pilot valve, briefly introduce:

1. A pilot control liquid bridge is formed with the fixed liquid resistance, and the main valve or the secondary valve or the variable lever is controlled according to the input signal;

2. The input signals are relatively small;

3. Can accept a variety of input methods, such as manual, electric, hydraulic, pneumatic, mechanical cam, electrical ratio, etc .;

4. The flow of the first-stage pilot valve is generally only about 1 liter / minute and 3 liter / minute. The flow rate of the secondary pilot valve should be determined according to actual needs;

5. In the case of variable pump control, a variety of pilot valves form a modular structure, and a variety of functions are convenient to choose;

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