The Sun Hydraulics DNDMDNV (DNDMDNV) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling the flow direction in hydraulic circuits. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism, specifically engineered for intermittent and infrequent use. The valve offers multiple control options: the momentary-twist option (T) allows temporary shifting by twisting the knob clockwise, with automatic return upon release; the detent-lock option (L) enables shifting into a mechanically locked position by twisting counterclockwise, maintained until manually reset; and the dual-operation option (D) combines both functionalities. Importantly, the detented position is not suitable for load-holding applications but is intended for temporary shifts only. The valve's manual control should be operated exclusively by hand without any modifications or mechanical device assistance. Designed with Sun's floating style construction to prevent internal part binding from excessive torque or machining variations, this cartridge fits into a T31A cavity and belongs to Series 1. It has a capacity of 10 gpm (40 L/min) and can handle a maximum operating 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). Operating torque required is 10 lbf\u00b7in (1.2 Nm), with an installation torque range between 30 to 35 lbf\u00b7ft (41 to 47 Nm). For systems using phosphate ester fluids, cartridges equipped with EPDM seals are recommended due to their incompatibility with petroleum-based fluids. 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.
