The Sun Hydraulics DNDMTRN (DNDMTRN) is a manually operated, 2-position, 4-way directional cartridge valve designed to control the direction of flow in hydraulic circuits. It features a direct-acting, balanced spool valve mechanism and utilizes Sun's TwistLock manual override for operation. This valve is specifically engineered for intermittent infrequent use, with a mechanical life expectancy of approximately 7,000 cycles. The DNDMTRN offers multiple control options including momentary twist (T), detent lock (L), and dual operation (D). The momentary twist option allows the operator to temporarily shift the valve by twisting the knob clockwise; it returns to its normal position upon release. The detent lock option enables shifting into a mechanically held position by twisting counterclockwise, which remains until reversed; however, this is not suitable for load-holding applications. The dual operation combines both functionalities for versatile control. It's crucial that this valve is operated manually by hand without any modifications or mechanical devices attached. It incorporates EPDM seals compatible with phosphate ester fluids but can be damaged by petroleum-based substances. The design includes Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. Key specifications include a T31A cavity, Series 1 with a capacity of 10 gpm (40 L/min), a maximum operating pressure of 5000 psi (350 bar), and maximum leakage at specified conditions of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Installation requires adherence to specific torque values: valve hex size is 7/8 in. (22.2 mm) with an installation torque range of 30 - 35 lbf\u00b7ft (41 - 47 Nm). A Viton seal kit is available under part number 990431006 for maintenance needs.

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.
