Forklift Pressure Relief Valve DGMC2-3-AT-CW-BT-BW-41

Forklift Pressure Relief Valve DGMC2-3-AT-CW-BT-BW-41: SystemStak Modular Dual Relief Valve

The DGMC2-3-AT-CW-BT-BW-41 is a SystemStak modular stackable dual relief valve for ISO 4401-03 / CETOP 3 / NG6 hydraulic manifolds. As a sandwich plate valve design, it mounts between the directional control valve and the manifold subplate, providing adjustable pressure relief protection without additional plumbing or external piping. This two-way, dual function valve handles flows up to 60 L/min (15.85 gpm) at 315 bar maximum, with an adjustable pressure range of 4-200 bar — making it suitable for forklift attachment circuits, mast tilt systems, and industrial hydraulic applications in excavators, wheel loaders, and injection molding machines.

Weighing 3.6 kg at 233x47x39 mm, this Vickers-compatible valve uses NBR or optional FKM seals rated for -20°C to +80°C mineral oil operation. The stackable modular design reduces manifold complexity by integrating the relief function directly into the valve stack rather than requiring a separate cartridge or inline relief valve. Common failure modes include spring fatigue causing pressure drift, O-ring deterioration at manifold interfaces causing external leakage, and poppet seat wear from contaminated oil leading to failure to hold set pressure. Backed by a 1-year warranty with 3-7 day lead time.
