Manifold – MDR06

The Polyhydron MDR06 is a compact hydraulic manifold block used to mount standard size 6 directional control valves. It acts as a central hub that connects your pump, tank, and actuators while providing a dedicated port for a pressure relief valve. By consolidating these connections into one block, it reduces the need for complex piping, prevents leaks, and saves significant space in industrial hydraulic power units.
