The Sun Hydraulics DMDMDNN (DMDMDNN) is a manually operated, 2-position, 3-way directional cartridge valve designed for controlling the direction of flow in hydraulic circuits. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism, intended primarily for intermittent and infrequent use. The DMDMDNN offers multiple control options including momentary-twist control (option T), which allows temporary shifting of the valve by twisting the knob clockwise; upon release, the valve reverts to its default position. The detent-lock control (option L) enables shifting into a mechanically detented position by twisting counterclockwise, maintaining this state until deliberately reversed. Additionally, the dual-operation control (option D) combines both functionalities. This model is engineered with 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 exhibits maximum valve leakage at 5 in\u00b3/min at 3000 psi. The operating torque required is relatively low at 10 lbf\u00b7in (1.2 Nm), facilitating ease of manual operation. Installation specifications include a valve hex size of 7/8 in (22.2 mm) and an installation torque ranging from 30 to 35 lbf\u00b7ft (41 to 47 Nm). The cartridge utilizes Viton seals for enhanced durability under various operating conditions. The construction of the DMDMDNN incorporates Sun's floating style design which minimizes potential internal part binding that could result from excessive installation torque or variations in cavity/cartridge machining. This thoughtful engineering ensures reliable performance and longevity of the valve even under demanding circumstances.

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.
