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 appliions (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 loed 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.
