1.What is A pilot valve?

A pilot valve is a small valve that controls a limited-flow control feed to a separate piloted valve. Typically, this valve controls a high pressure or high flow feed. Pilot valves are useful because they allow a small and easily operated feed to control a much higher pressure or higher flow feed, which would otherwise require a much larger force to operate; indeed, this is even useful when a solenoid is used to operate the valve.

Pilot valves are often used in critical applications (i.e., emergency and safety controls) and are human-operated. They can be set up as a push-to-activate or dead man's switch.

Pilot valve set-point

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 (2).
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.
The spring selection is usually done by “DOROT” technical department according to the client’s data and demands but spring replacement can be easily done by the client if conditions demand.
