The Sun Hydraulics DNDMLNE (DNDMLNE) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling the direction of flow in a hydraulic circuit. This direct-acting, balanced spool valve features Sun's Twist-Lock manual override mechanism, which is intended for intermittent and infrequent use. The valve offers multiple control options: the momentary-twist control option allows temporary shifting by twisting the knob clockwise; the detent-lock option enables the valve to remain in a mechanically detented position until manually reset; and the dual-operation option combines both functionalities. Notably, the detented position is not suitable for load-holding applications but rather for temporary shifting purposes. The DNDMLNE model incorporates Sun's floating style construction to reduce potential binding of internal parts due to excessive installation torque or machining variations. It fits into a T-31A cavity and belongs to Series 1 with a capacity of up to 10 gpm (40 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve has a maximum leakage rate of 10 cubic inches per minute at 3000 psi (160 cc/min at 210 bar) when using fluid with viscosity of 110 SUS (24 cSt). The operating torque required is 10 lbf-in (1.2 Nm), and it should be installed with a torque between 30 to 35 lbf-ft (41 to 47 Nm). It is crucial that this valve be operated solely by hand without any mechanical modifications or additions such as levers. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended as exposure to petroleum-based fluids could damage these seals. Furthermore, this product is equipped with Viton seal kits under part number 990431006 for additional compatibility and maintenance needs.

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.
