Danfoss DGMDC-3 / DGMDC-5 Hydraulic Direct Check Valve
Modular hydraulic check valves for one-way flow control, reverse-flow protection and compact integration into industrial hydraulic systems.
Compact Check Valve for Modern Hydraulic Circuits
Danfoss DGMDC-3 and DGMDC-5 are direct-operated SystemStak hydraulic check valves designed to control hydraulic fluid in one direction and restrict reverse flow.
Their modular sandwich construction allows the valve to be integrated into a stacked hydraulic manifold. This design is useful when equipment manufacturers require a compact hydraulic valve solution with fewer external connections.

How the DGMDC Check Valve Controls Hydraulic Flow
When hydraulic pressure acts in the permitted flow direction, the internal check mechanism opens to allow fluid to pass through the valve.
When pressure attempts to reverse the flow direction, the internal check element closes and restricts unwanted return flow. This makes the DGMDC suitable for hydraulic circuits where directional flow control is required.
Hydraulic pressure reaches the valve.
The check mechanism permits the required flow.
The valve restricts unwanted reverse flow.
