The Sun Hydraulics DMDMLPN (DMDMLPN) is a manually operated, 2-position, 3-way directional cartridge valve designed for hydraulic circuit control. This direct-acting, balanced spool valve facilitates manual operation through Sun's TwistLock manual override mechanism, intended primarily for intermittent and infrequent use. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). Its design incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The DMDMLPN offers three control options: momentary-twist (T), detent-lock (L), and dual-operation (D). The momentary-twist control allows the operator to temporarily shift the valve by twisting the knob clockwise; upon release, the valve automatically returns to its original position. The detent-lock option enables shifting the valve into a mechanically detented position by twisting the knob counterclockwise; this position is maintained until manually reverted. The dual-operation control combines both functionalities, providing flexibility depending on operational needs. It is crucial to note that these detented positions are not suitable for load holding but are meant for temporary shifting only. This model requires an installation torque of 30-35 lbf ft (41-47 Nm) and features a hex size of 7/8 in. (22.2 mm). The mechanical life expectancy of its manual control assembly is approximately 7,000 cycles, emphasizing its durability for specified applications. Additionally, the valve exhibits minimal leakage at high pressures with a maximum rate noted at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The operational torque required is relatively low at about 10 lbf in. (1.2 Nm), ensuring ease of manual operation without necessitating modifications or mechanical aids.
