Differential Relief Valve (Cartridge)
A high-capacity differential (sense-area) relief valve rated to 400 bar and 160 l/min. The differential design offers lower cracking pressure sensitivity at high flow — it is the relief valve of choice for high-flow main-line circuits in industrial and mobile plant hydraulics where stable, consistent cracking behaviour is required.
Two setting ranges cover 20–400 bar, and the standard adjustment is a screw with steel cap.
