What Is the Danfoss DGMDC Hydraulic Check Valve?
The Danfoss DGMDC-3 and DGMDC-5 are SystemStak direct-operated hydraulic check valves developed for one-way flow control in hydraulic circuits. The valve permits hydraulic fluid to move through the selected flow direction and restricts unwanted reverse flow.
Unlike conventional inline hydraulic check valves, the DGMDC series uses a modular sandwich valve configuration. This allows the valve to be installed directly within a stacked hydraulic manifold assembly, reducing additional piping and helping create a cleaner hydraulic system layout.
The DGMDC-3 and DGMDC-5 are commonly selected when hydraulic equipment designers need a compact modular check valve for hydraulic power units, industrial machines, presses, cylinders, actuators and material handling equipment.

Engineering Features That Matter in Hydraulic Systems
Controlled One-Way Flow
The check valve design allows hydraulic fluid to pass in the intended direction while restricting reverse flow.
SystemStak Installation
Sandwich-style installation allows the DGMDC valve to become part of a compact stacked hydraulic manifold.
Compact Hydraulic Layout
Modular construction can reduce the need for additional external piping and supports around the valve assembly.
Replacement Friendly
Suitable for hydraulic system repair, spare parts sourcing, equipment refurbishment and OEM replacement requirements.
Where DGMDC Hydraulic Check Valves Are Used
Designed for hydraulic circuits where reliable directional flow control and compact valve stacking are important.
Circuit flow management and reverse-flow prevention.
Hydraulic cylinder and actuator circuit applications.
Compact hydraulic control and manifold systems.
Hydraulic actuator and equipment control circuits.
Mobile hydraulic systems requiring directional flow control.
Hydraulic control systems used in automated machinery.
How to Choose the Correct DGMDC Model
Selecting a DGMDC hydraulic check valve should start with the mounting standard and hydraulic circuit requirements. DGMDC-3 and DGMDC-5 are not simply interchangeable because their mounting interfaces are different.
Before ordering, buyers should confirm the complete valve model, mounting size, flow requirement, operating pressure, flow direction, cracking pressure, seal material and hydraulic fluid compatibility.
