The Sun Hydraulics DNDMLTV (Material Number: DNDMLTV) is a manually operated, 2-position, 4-way directional cartridge valve designed to control the direction of flow in hydraulic circuits. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism, ideal for intermittent and infrequent usage. It offers multiple control options: the momentary-twist option (T) allows temporary shifting by twisting the knob clockwise and releasing it, while the detent-lock option (L) enables shifting into a mechanically detented position by twisting counterclockwise. The dual-operation control option (D) provides both momentary and detented operation capabilities. However, the detented position is not suitable for load-holding applications but rather for temporary shifting. Designed for operation by hand only, this valve should not be modified with mechanical devices or levers to avoid damage or malfunction. It incorporates EPDM seals specifically suited for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve is robust and reliable under demanding conditions. The valve's construction minimizes internal binding risks due to excessive installation torque or machining variations. The DNDMLTV fits into a T-31A cavity with a series number of 1 and requires an installation torque between 30 to 35 lbf ft (41 to 47 Nm). It features a leakage rate of up to 10 in\u00b3/min at 3000 psi and an operating torque requirement of 10 lbf in (1.2 Nm). For maintenance, 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.
