Stacking Sequence and Preload Valve series SDVB-3

Pressure [bar]


Flow rate [l/min]


SeriesSDVB–3…–6 stack valve sare used for sequence and preload functions. They are equipped with the two-stage pressure relief cartridge type DVPA–3–10… When closed, the valves shut off the relief path with spool type leakage (see performance data).The pilot stage of the cartridge is drained to port T – the pressure setting is therefore unaffected by fluctuations of the secondary pressure in P1, A1 or B1. The bypass check valve in models SDVB–3–AAAR–6…and SDVB–3–BBAR–6… allows reverse flow from A1 to A or B1 to B.

NOTE: After the connection P–P1 (or A–A1,B–B1) has opened, pilot oil drain flow to T will increase with rising system pressure (see performance data).The screw  in design of the cartridge valve provides for straight forward, trouble free maintenance. Interface sealing is by means of O-rings which are retained in counterbores in the valve body.
