The Sun Hydraulics DMDMDAN (DMDMDAN) is a manually operated, 2-position, 3-way directional cartridge valve designed for controlling the direction of flow in hydraulic circuits. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism, tailored specifically for intermittent and infrequent use. The valve is equipped with multiple control options: the momentary-twist control option T allows temporary shifting by twisting the knob clockwise; the detent-lock control option L enables shifting into a mechanically detented position by twisting counterclockwise; and the dual-operation control option D combines both functionalities. It is crucial to note that these detented positions are not intended for load holding but for temporary engagement only. The manual control assembly of the DMDMDAN valve is robust, with a mechanical life expectancy of about 7,000 cycles. The valve operates efficiently within a hydraulic system with a maximum capacity of 12 gpm (45 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It exhibits minimal leakage at high pressures and incorporates Sun's floating style construction to reduce internal parts binding. This construction also ensures consistent performance even when variations in installation torque and cavity/cartridge machining occur. This valve should be operated manually and any modifications to attach mechanical devices or levers to the control knob are strongly discouraged to maintain safety and integrity. The installation specifications include an operating torque of 10 lbf\u00b7in (1.2 Nm), a hex size for the valve at 7/8 in (22.2 mm), and an installation torque between 30 - 35 lbf\u00b7ft (41 - 47 Nm). The seal kit used with this cartridge utilizes Viton components, ensuring durability and resistance under various operational conditions.
