The Sun Hydraulics DMDMDRV (DMDMDRV) is a manually operated, 2-position, 3-way directional cartridge valve designed for use in hydraulic circuits. This direct-acting, balanced spool valve is primarily intended for intermittent and infrequent manual override applications. It features Sun's TwistLock manual override mechanism which enhances operational safety and efficiency. The DMDMDRV offers multiple control options including momentary-twist (option T), detent-lock (option L), and dual-operation (option D). The momentary-twist control allows the operator to temporarily shift the valve by twisting the knob clockwise; upon release, the valve automatically returns to its original position. The detent-lock option enables the valve to be locked in a mechanically detented position by twisting the knob counterclockwise, which remains until manually reset. The dual-operation combines both functionalities depending on the direction of twist. This valve has a mechanical life expectancy of around 7,000 cycles and incorporates Sun's floating style construction to minimize internal binding caused by installation torque or machining variations. It operates with a maximum flow capacity of 12 gpm (45 L/min) and can withstand pressures up to 5000 psi (350 bar). Additional specifications include a maximum leakage of 5 in\u00b3/min at 3000 psi, an operating torque of 10 lbf\u00b7in., and typical installation torque requirements between 30 - 35 lbf\u00b7ft. Designed specifically for hand operation, any modifications such as attaching levers or other mechanical devices to the control knob are strongly discouraged to ensure safety and proper functionality. This robust construction and versatile control options make the DMDMDRV an excellent choice for hydraulic systems requiring reliable manual intervention capabilities.

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.
