The Sun Hydraulics DNDMDYN (DNDMDYN) is a manually operated, 2-position, 4-way directional cartridge valve designed to control the direction of flow in a hydraulic circuit. This direct-acting, balanced spool valve features Sun's Twist-Lock manual override mechanism for intermittent and infrequent use. It has a mechanical life expectancy of approximately 7,000 cycles. The valve offers multiple control options: the momentary-twist option (T) allows for temporary shifting by twisting the knob clockwise; the detent-lock option (L) enables shifting into a mechanically detented position by twisting counterclockwise; and the dual-operation option (D) provides both functionalities. The detented position is not suitable for load holding but rather for temporary shifting. The valve should only be operated manually without any modifications or mechanical devices attached to the control knob. The DNDMDYN is compatible with systems using phosphate ester fluids due to its EPDM seals, which are vulnerable to petroleum-based substances. It incorporates Sun's floating style construction, minimizing internal binding risks from excessive installation torque or machining variations. With a cavity size of T-31A and series 1, this cartridge has a capacity of 10 gpm (40 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Its maximum valve leakage at 110 SUS (24 cSt) is rated at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Operating torque is specified at 10 lbf-in (1.2 Nm), with an installation torque range between 30 to 35 lbf-ft (41 to 47 Nm). The valve hex size measures at .78 inches (22.2 mm), and it includes a Viton seal kit with 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.
