The DGMPC-3-ABK-BAK-41 belongs to the SystemStak Modular Valve series from Vickers and serves as a pilot-operated check valve for hydraulic automation circuits. It is pressure operated, so a remote pilot signal opens the poppets when required, and it guards both A and B ports against reverse flow. The valve opens when system pressure rises above a cracking pressure of 1 bar (15 psi), letting flow proceed only after that threshold is reached. Internal passages are built to pass up to 60 L/min (16.0 US gpm) without excessive pressure drop, and the body withstands a maximum operating pressure of 315 bar (4500 psi) for high-duty applications. Connection to adjoining sandwich modules follows the ISO 4401-03 mounting pattern, allowing straightforward stacking in compact manifolds.
Installation is subplate or manifold mounted, matching the modular construction style of SystemStak assemblies. Viton seals provide compatibility with petroleum oils and resist temperatures encountered in mobile or industrial power units. The valve operates reliably between −20 °C (−4 °F) and 80 °C (176 °F), so it covers typical ambient and fluid conditions found in machinery. A fluid cleanliness level of 19/17/14 is required to limit wear on internal moving parts and maintain tight seating. These characteristics enable the valve to hold actuator loads securely, respond to pilot release signals, and integrate easily into stacked hydraulic control stations.
