The Sun Hydraulics DMDMLNN (DMDMLNN) is a manually operated, 2-position, 3-way directional cartridge valve designed primarily for directing flow in hydraulic circuits. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism, suitable for intermittent and infrequent use. The valve offers several control options including a momentary-twist control (option T), which allows the operator to temporarily shift the valve by twisting the knob clockwise; upon release, the valve reverts to its original position. Alternatively, the detent-lock control (option L) enables shifting into a mechanically detented position by twisting counterclockwise, maintaining this position until manually reverted. The dual-operation control (option D) combines both functionalities. This model is built for manual operation and has a mechanical life expectancy of around 7,000 cycles. It is not intended for load holding but for temporary shifting only. Important specifications include a flow capacity of 12 gpm (45 L/min), a maximum operating pressure of 5000 psi (350 bar), and maximum leakage at 3000 psi being 5 in\u00b3/min. The operating torque is relatively low at approximately 10 lbf\u00b7in (1.2 Nm), ensuring ease of manual operation without requiring excessive force. Constructed with Sun's floating style design, the DMDMLNN minimizes potential internal binding caused by excessive installation torque or variations in cavity/cartridge machining. This enhances reliability and performance consistency in various hydraulic applications. The overall design and build of this valve ensure that it meets high standards of durability and operational efficiency suited for specific hydraulic control tasks where manual intervention is necessary.

This manually operated, 2-position, 3-way directional cartridge is a direct-acting, balanced spool valve used to control the direction of flow in a hydraulic circuit. Manual operation is achieved via Sun's Twist/Lock manual override mechanism and is designed for intermittent (infrequent) use only.
- This valve is designed for intermittent use such as a manual override. The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- The momentary/twist control option "T" allows the operator to momentarily shift the valve by twisting the knob clockwise and releasing. Once released, the valve returns to its normal position.
- The detent/lock control option "L" allows the operator to shift the valve into a mechanically detented position by twisting the knob counter-clockwise. This detented position will be maintained until the operator twists the knob clockwise and allows the valve to return to its normal position. Please note that the detented position is not intended for load holding applications but for temporary shifting only.
- The dual-operation control option "D" allows the operator to either shift the valve momentarily by twisting the knob clockwise or shift it into a mechanically detented postion by twisting counter-clockwise. Please note that the detented position is not intended for load holding applications but for temporary shifting only.
- The control on this valve is meant to be operated by a person's hand. The control should not be modified, for instance fastening a lever to the knob. Under no circumstances should the control be operated by other mechanical devices.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
