The Sun Hydraulics DNDMLRE (DNDMLRE) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling flow direction in hydraulic circuits. This direct-acting, balanced spool valve utilizes Sun's Twist-Lock manual override mechanism, intended for intermittent and infrequent use. It features a mechanical life expectancy of approximately 7,000 cycles. The DNDMLRE offers three control options: the momentary-twist option (T), which allows temporary shifting by twisting the knob clockwise; the detent-lock option (L), enabling a mechanically detented position by twisting counterclockwise; and the dual-operation option (D), combining both functionalities. Notably, the detented position is not suitable for load-holding applications but is intended for temporary shifting only. The valve is designed to be hand-operated and should not be modified or used with other mechanical devices. It incorporates EPDM seals compatible with systems using phosphate ester fluids while being vulnerable to petroleum-based fluids. The DNDMLRE features Sun's floating-style construction to reduce internal binding risks due to excessive installation torque or cavity machining variations. This valve fits into a T-31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar) and has a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar) when using oil with viscosity of 110 SUS (24 cSt). The operating torque required is 10 lbf-in (1.2 Nm). Its hex size measures 7/8 inch (22.2 mm), and it should be installed with a torque between 30 - 35 lbf-ft (41 - 47 Nm). The recommended seal kit for this cartridge uses Viton material, specifically 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.
