The Sun Hydraulics DNDMLCV (DNDMLCV) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling the direction of flow within a hydraulic circuit. This direct-acting, balanced spool valve features Sun's Twist-Lock manual override mechanism, intended for intermittent and infrequent use. It offers three control options: momentary-twist (T), detent-lock (L), and dual-operation (D). The momentary-twist option allows the valve to briefly shift when the knob is twisted clockwise and released. The detent-lock option enables the valve to remain in a mechanically detented position when twisted counterclockwise until it is returned by twisting clockwise. The dual-operation option provides flexibility by allowing both momentary shifting and detented positioning. However, the detented position is not suitable for load holding applications and should only be used for temporary shifting. This cartridge valve incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It is designed with a T31A cavity, Series 1, supporting a capacity of up to 10 gpm (40 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is rated at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The operating torque required is 10 lbf-in (1.2 Nm), with an installation torque range of 30-35 lbf-ft (41-47 Nm). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended, as exposure to petroleum-based fluids may damage these seals.

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.
