Apr 22, on a hydraulic circuit with a fixed-displacement pump, a direct-acting relief valve opens partially early and thus wastes energy. when the system must operate near maximum pressure without any fluid bypass, use a pilot-operated relief valve. fig 18-2. simplified symbol for a pilot.
Aug 15, another style of line commonly used is the dash-dot boundary or enclosure line. this represents a grouping of hydraulic components as part of a compound component (such as a pilot operated directional valve, with both pilot and main stage valve together), a sub circuit (such as a safety circuit for a hydraulic press) or a stand.
