The DGMPC5BAK30 valve belongs to the SystemStak Modular Valves series produced by Vickers for stacked hydraulic control assemblies. It provides pilot-operated check functionality in automated circuits where pressure sequencing is required. The valve is pressure operated and matched to CETOP size 5 patterns, while the NFPA D05 designation allows straightforward interchange on common manifold plates. An ISO 4401-AC-05-4-A mounting interface supports direct stacking without additional adapters. Flow passes through pilot port A and is retained by a 3:1 pilot area ratio that ensures reliable opening under differential pressure. The check port is on B and unseats when cracking pressure reaches 1.0 bar (15 psi). There is no decompression feature, so pressure equalization must be handled elsewhere in the circuit.
Rated working limits make the DGMPC5BAK30 suitable for demanding mobile or industrial stations. Maximum operating pressure is 315 bar (4500 psi), and the valve accommodates up to 120 L/min (32 US gpm) without excessive drop. It is intended for petroleum oils and should be supplied with hydraulic fluid meeting a cleanliness class of 19/17/14 to maintain poppet life. Internal leakage is limited to 0.3 ml/min when the poppet is held at 35 bar and 50 °C, supporting energy-efficient holding. These capacity margins let the module serve as a secure locking element in high-pressure circuits. Physical data simplify integration: overall height is 50.038 mm (1.970 in) and mass is 2.9 kg (6.4 lb), which keeps stack height and weight within common manifold tolerances.
