Sun Hydraulics DMDA-MAN Directional Spool Valve

Sun Hydraulics DMDA-MAN Directional Spool Valve is a manually actuated directional control valve that uses a spool to route hydraulic fluid between ports in a circuit. The DMDA-MAN designation identifies manual actuation, with an actuation force of approximately 30–35 lbf required to shift the spool. This valve provides straightforward flow-direction control in hydraulic systems where operator input is preferred or required, offering a compact, robust option for applications that do not rely on electrical pilot actuation. By enabling precise direction changes with a simple hand-operated action, the DMDA-MAN valve helps simplify hydraulic circuit design and maintenance in equipment and tooling that benefit from manual control. Designed for compact installations, it fits into hydraulic manifolds where space is limited, and its spool-based action supports reliable blocking, routing, or redirecting of flow as needed. The DMDA-MAN variant represents Sun Hydraulics’ approach to combining dependable performance with a manual interface suitable for operations that require direct operator involvement in valve control.
