The Sun Hydraulics DNDMDRN (DNDMDRN) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling the flow direction in hydraulic circuits. It features Sun's Twist-Lock manual override mechanism, intended for intermittent and infrequent use. This valve is suitable for applications requiring manual overrides, with a mechanical life expectancy of approximately 7,000 cycles. It offers three control options: the momentary-twist option (T), which allows temporary shifting by twisting the knob clockwise; the detent-lock option (L), which holds the valve in a detented position until manually released; and the dual-operation option (D), combining both momentary and detent functions. Note that the detented position is not meant for load-holding applications but rather for temporary shifts. The DNDMDRN valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. It operates at a maximum capacity of 10 gpm (40 L/min) and can handle pressures up to 5000 psi (350 bar). The valve has a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar) under specific conditions. It requires an operating torque of 10 lbf-in (1.2 Nm) and an installation torque between 30-35 lbf-ft (41-47 Nm). The valve fits into a T-31A cavity and utilizes Viton seals, with EPDM seals available for systems using phosphate ester fluids\u2014note that exposure to petroleum-based fluids can damage these seals. This product is engineered for precise manual operation by hand, without modifications or mechanical assistance. Its robust design ensures reliable performance in appropriate hydraulic applications where direct control over fluid direction is necessary.

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.
