The Sun Hydraulics DNDMLTN (DNDMLTN) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling flow direction in hydraulic circuits. Featuring a direct-acting, balanced spool design, this valve utilizes Sun's Twist-Lock manual override mechanism, making it ideal for intermittent and infrequent manual operations. The valve offers three control options: momentary-twist (T), detent-lock (L), and dual-operation (D). The momentary-twist allows temporary shifting by twisting the knob clockwise and releasing it to return to its normal position. The detent-lock enables the valve to remain in a mechanically detented position when twisted counterclockwise, but it's not suitable for load holding. Dual-operation combines both functionalities. This control should be operated by hand only and should not be modified with levers or mechanical devices. The DNDMLTN is constructed with Sun's floating style to reduce internal binding risks due to installation torque or machining variations. It fits into a T-31A cavity and belongs to Series 1 with a flow capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar). Leakage is minimal at a 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), with installation torque ranging from 30 to 35 lbf-ft (41 to 47 Nm). It's important that cartridges with EPDM seals are used exclusively with phosphate ester fluids as petroleum-based substances can damage them. For maintenance or replacement, 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.
