The Sun Hydraulics DNDMTRV (DNDMTRV) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling flow direction in hydraulic circuits. This direct-acting, balanced spool valve utilizes Sun's TwistLock manual override mechanism, making it suitable for intermittent and infrequent use. It features a mechanical life expectancy of approximately 7,000 cycles and offers various control options: the momentary-twist control (T), detent-lock control (L), and dual-operation control (D). The momentary-twist option allows temporary shifting by twisting the knob clockwise; upon release, the valve returns to its normal position. The detent-lock option keeps the valve in a mechanically detented position when twisted counterclockwise and is not intended for load holding. The dual-operation control provides both momentary and detented shifting capabilities. This valve should be hand-operated only and not modified with levers or mechanical devices. The DNDMTRV incorporates Sun's floating style construction to reduce binding risks from excessive installation torque or machining variations. It fits into cavity T-31A, belongs to series 1, and has a capacity of 10 gpm/40 L/min with a maximum operating pressure of 5000 psi/350 bar. 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 set at 10 lbf-in./1.2 Nm, while installation torque ranges between 30-35 lbf-ft/41-47 Nm. Cartridges are compatible with EPDM seals for phosphate ester fluids; petroleum-based substances can damage these seals. Viton seal kit number is 990431006 for maintenance purposes.

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.
