Pilot valve *** with the same characteristics
1) and fixed liquid resistance to form a pilot control bridge, according to the input signal to the main valve or secondary valve or variable bar control;
2) the first level of the pilot valve flow is generally only about 1 liters / min, the maximum of 3 liters / min. The flow rate of the secondary pilot valve should be decided according to the actual need.
3) the input signal is relatively small;
4) can accept a variety of input modes, such as manual, electric, hydraulic, pneumatic, mechanical cam, electric proportional, etc.;
5) in the variable pump control and other situations, a variety of pilot valves to form a modular structure, a variety of functions to take a convenient;
6) pilot valves are often a small size of the control valves, mostly pressure control valves. Mostly pressure control valves.
