About this document
Pilot Pressure Sequence Valve Overview by simpitok14 is a document available to read on EtoBox.
The pilot pressure sequence valve is a non-adjustable valve that maintains a preset pressure of 200 psi for the dump/hoist/steering pilot circuit, with excess oil directed to the brake cooling circuit. An internal check valve prevents the brake cooling circuit pressure from exceeding 65 psi, and if the sequence valve fails, it must be replaced. Additionally, the accumulator pressure switch activates at 1,400 psi, signaling the operator through indicator lights when pressure drops below this threshold.
