Hydraulic Pilot Valve Describe

Hydraulic pilot valves have a predetermined pressure setting that dictates when the pilot valve opens and closes. As pressure builds up around the pilot valve, the pressure sensor determines when the valve should open. The pilot valve will then release hydraulic fluid into the other valves until the pressure setting is below the maximum pressure. The secondary valves are completely dependent on the pilot valve. If the pilot breaks or malfunctions in any way, the entire hydraulic system becomes unusable.

A hydraulic system is powered by a pump designed to provide a certain amount of continuous pressure. A bigger and more powerful pump can pump hydraulic fluid faster, but it also uses a lot more energy. A hydraulic accumulator is a system which stores pressurized hydraulic fluid. That way, the pump does not have to be powerful enough to cope with a sudden surge in demand. Instead, it can keep steadily pumping hydraulic fluid and rely on the accumulator to provide extra hydraulic fluid when it is needed.

Application

The pilot valve’s position is determined by the forces equilibrium of hydraulic pressure and spring resistance.
Spring resistance is adjusted by the adjustment bolt.
Compressing the spring (turning the bolt in clock-wise direction) increases the regulated parameter. For example: In Pressure Reducing valves- tightening the bolt (turning in clock-wise direction) will increase the maximal downstream pressure. In Pressure Sustaining valves- tightening the bolt will increase the minimal upstream pressure. In Flow Control valves- tightening the bolt will increase the maximal flow rate.
A specific spring has specific pressure range in which it can regulate. Springs are marked by different colors representing different pressure ranges. Correct spring selection is critical for the Pilot valve function.
Colored rings located on the adjustment bolt specify the internal spring color.
