Pressure Sequence Valves .
DZ5 / DZ6 / DZ10 Direct & Pilot Series
Pressure sequence valves — direct-operated (DZ5DP, DZ6DP, DZ10DP) and pilot-operated (DZ10…30B) — for automating hydraulic cycles. Setting range up to 21 MPa, rated flow up to 60 l/min (DZ6) or 300 l/min (DZ10), 5 spring ranges. Variants M / XM / YM / XYM differ by external control and drain signal routing. Used for sequential circuit activation (clamp → press), backup cylinder engagement once pressure is reached, pressure-line separation and press-cycle coordination.
