Vickers Hydraulic Relief Valve DGMPC-5-ABK-BAK-30 For Pressure Limitation

Danfoss SystemStak™ valves make compact hydraulic systems in which modular valves are "sandwich" mounted between a directional valve and a standard mounting surface. Compact design improves system response by elimination of external fluid conductors, thereby resulting in elimination of resonant sounds which are noisy and lead to leakage.

The design of these valves is well proven and offers opportunities for achieving small control assemblies, especially when the valves are used with multi-station manifolds. Mounting surface is available for interfacing with directional valves and is coded "5" in the model numbers of Danfoss SystemStak valves. The "5" interface accepts Danfoss DG4S4 directional valves and other directional valves with a standard ISO 4401-05, NFPA-D05, ANSI/B93.7M size D05 or CETOP-5 port pattern. Each valve "stak" can be configured to provide the specific combination of functions required to meet the system's needs.

These two-stage valves limit system pressure by directing flow to tank or the opposite cylinder port (A-B/B-A crossport types) when system pressure reaches the valve setting. Pressure control may be obtained in "A", "B", "A" and "B" or "p" port, and pilot flow may be internally or externally drained, depending on model type. Any pressure in the line to which these valves are drained is additive to the valve pressure setting.

The valve pressure setting is adjustable by means of either an adjusting screw and locknut, a hand-knob adjuster, or a micrometer knob with keylock. External remote control/vent connections are available on all models except crossport relief. If required on crossport models, contact your Danfoss representative.
