The Sun Hydraulics DNDMDYV (DNDMDYV) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling the flow direction in hydraulic circuits. This direct-acting, balanced spool valve utilizes Sun's TwistLock manual override mechanism and is specifically engineered for intermittent and infrequent use. The valve offers different control options: the momentary-twist control (option T) allows temporary shifting by twisting the knob clockwise, while the detent-lock control (option L) maintains a mechanically detented position until shifted back. The dual-operation control (option D) combines both functionalities for versatile operation. It is essential to note that the detented position is not suitable for load-holding applications but rather for temporary shifts. The valve should be operated manually without any mechanical modifications or attachments to the knob. This cartridge valve features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with a maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Operating torque required is approximately 10 lbf-in (1.2 Nm), and it requires an installation torque between 30 - 35 lbf-ft (41 - 47 Nm). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended, as exposure to petroleum-based fluids can damage these seals.

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.
