The Sun Hydraulics DNDMLCN (DNDMLCN) is a manually operated, 2-position, 4-way directional cartridge valve designed to control the flow direction in hydraulic circuits. This direct-acting, balanced spool valve utilizes Sun's TwistLock manual override mechanism, making it suitable for intermittent and infrequent use. It offers multiple control options: momentary-twist (T), detent-lock (L), and dual-operation (D). The momentary-twist option allows temporary shifting by twisting the knob clockwise, while the detent-lock option holds the valve in a mechanically detented position until manually reset. The dual-operation control combines both functionalities. Note that the detented position is not for load-holding applications but for temporary shifts only. The valve is hand-operated and should not be modified with levers or other mechanical devices. It features EPDM seals compatible with phosphate ester fluids but vulnerable to petroleum-based substances. Constructed with Sun's floating style design, it minimizes internal part binding due to excessive torque or machining variations. The DNDMLCN fits into a T-31A cavity and belongs to Series 1, offering a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar). Valve leakage at 110 SUS (24 cSt) is limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Operating torque is rated at 10 lbf\u00b7in (1.2 Nm), with installation torque between 30-35 lbf\u00b7ft (41-47 Nm). It comes with Viton seal kit part number: 990431006.

This manually operated, 2-position, 4-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.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
