The Sun Hydraulics DMDMLBN (DMDMLBN) is a manually operated, 2-position, 3-way directional cartridge valve designed primarily for hydraulic circuits requiring intermittent control through manual intervention. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism, which is specifically engineered for infrequent use. The valve offers three control options: momentary-twist (T), detent-lock (L), and dual-operation (D). The momentary-twist option enables temporary shifting by twisting the knob clockwise; upon release, the valve returns to its original position. In contrast, the detent-lock option allows the valve to remain in a shifted position until manually reset by twisting the knob clockwise. The dual-operation option combines both functionalities. This product has a mechanical life expectancy of about 7,000 cycles and operates with a maximum flow capacity of 12 gpm (45 L/min) and can withstand pressures up to 5000 psi (350 bar). It also features minimal internal leakage at high pressures. Notably, its design incorporates Sun\u2019s floating style construction which helps minimize internal part binding due to installation torque or cavity-cartridge machining variations. The DMDMLBN is constructed to ensure it is operated manually by hand without modifications such as attaching levers or other mechanical devices. It has specific installation requirements including a recommended torque of 30 - 35 lbf ft (41 - 47 Nm) and uses a Viton seal kit for enhanced performance under various operating conditions. This product's robust design and versatile control options make it suitable for applications where manual control of hydraulic flow direction is necessary but not frequently required.

This manually operated, 2-position, 3-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.
- 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.
