When the system pressure reaches a certain level, an external pilot signal is sent to the valve. This signal exerts a force on the opposite end of the valve spool, overcoming the spring’s resistance and causing the spool to shift. When this happens, the pump’s output...
This reduces the pressure across the spool, which in turn moves the spool towards the closed position, counteracting the spring’s force and reducing flow. The pilot valve is crucial to the operation of this system, as it ensures that the main valve spool or...
