The DGMPC5ABK30 valve is supplied by Vickers within the SystemStak Modular Valves series. It functions in hydraulic automation to block reverse flow and hold loads as a PO check valve. The unit is pressure operated, so pilot pressure opens the poppet without external actuation. It acts on the A cylinder port, allowing directional valves upstream to relieve pressure while maintaining load security on the opposite side. A cracking pressure of 1 bar permits the poppet to unseat with minimal pilot signal, promoting quick response. The design tolerates operating pressures up to 315 bar, supporting heavy-duty industrial circuits. A maximum flow rate of 120 L/min governs sizing in medium flow manifolds. Installation follows the ISO4401-05 interface and uses a subplate or manifold mount so the valve can be stacked with other SystemStak modules without additional piping.
Viton seals are fitted to resist compression set and retain sealing quality with petroleum oils, the specified fluid family for this valve. System performance depends on maintaining fluid cleanliness at 19/17/14, which limits particle contamination that could erode the seat. The valve operates reliably up to a fluid temperature of 50 °C, ensuring elastomer stability under normal reservoir conditions. A compact height of 50.038 mm, width of 69.596 mm, and length of 147.828 mm match the SystemStak envelope so multiple functions fit within confined power units. These dimensional and material details support leak-free integration and long service life in modular hydraulic assemblies.
