The Sun Hydraulics DNDMLNV (DNDMLNV) is a manually operated, 2-position, 4-way directional cartridge valve designed to control the direction of flow in hydraulic circuits. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism for intermittent and infrequent use. The valve offers several 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, though it is not intended for load holding; and the dual-operation control option D combines both functionalities. The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles and should only be operated by hand without modification or external mechanical devices. The valve is suitable for systems using phosphate ester fluids when equipped with EPDM seals, as exposure to petroleum-based fluids will damage these seals. It incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. The valve fits into a T-31A cavity with a series 1 capacity of 10 gpm (40 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Maximum leakage is rated at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar). It requires an operating torque of 10 lbf\u00b7in (1.2 Nm) and should be installed with a torque of 30\u201335 lbf\u00b7ft (41\u201347 Nm). For maintenance, Viton seal kits are available under 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.
