The Sun Hydraulics DLDMDCV (DLDMDCV) is a manually operated, 2-position, 2-way directional cartridge valve designed for controlling the direction of flow in hydraulic circuits. It operates as a direct-acting, balanced spool valve and is available in either normally open or normally closed configurations. This valve features Sun's TwistLock manual override mechanism, tailored specifically for intermittent and infrequent use. Key operational modes include momentary-twist control (option T), which allows the operator to momentarily shift the valve by twisting the knob clockwise; upon release, it returns to its normal position. The detent-lock control (option L) enables shifting into a mechanically detented position by twisting the knob counterclockwise, maintaining this position until manually reverted. Additionally, the dual-operation control (option D) provides flexibility for either momentary shifting or locking into a detented position. Constructed with Sun\u2019s floating style design, the DLDMDCV minimizes potential internal binding caused by excessive installation torque or variations in cavity-cartridge machining. It has a mechanical life expectancy of around 7,000 cycles and should only be operated manually via hand. Any modification or mechanical operation beyond this recommendation is strongly discouraged to preserve integrity and functionality. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), this valve ensures robust performance in suitable applications. The maximum leakage at 110 SUS 24 cSt is limited to 5 in\u00b3/min at 3000 psi. Installation requires specific attention to torque settings between 30 - 35 lbf\u00b7ft (41 - 47 Nm) with an operating torque of about 10 lbf\u00b7in (1.2 Nm). The unit's compatibility with Viton seal kits further enhances its operational reliability and longevity under various conditions.
