The Sun Hydraulics DNDYLXV712N (DNDYLXV712N) is a solenoid-operated, 6-way, 2-position cartridge valve designed for selecting between two separate hydraulic circuits. In its de-energized state, it connects ports P and T to the first circuit, while energizing the solenoid switches the connection to the second circuit. This direct-acting valve requires no minimum hydraulic pressure for operation and is rated for a fatigue service of up to 5000 psi (350 bar). The valve features a unique wet armature design that allows working fluid to surround the armature, with caution advised for long-term coil energization due to potential fluid breakdown in certain mixtures like water-glycol. It offers several manual override options, though these are incompatible with weatherized coils. A standout feature is its high-efficiency solenoid that provides significant spool actuating force per watt, ensuring reliable valve shifting. The DNDYLXV712N is constructed using Sun's floating style design to minimize internal binding risks due to installation torque or machining variations. It supports a capacity of up to 5 gpm (20 L/min) and maintains a maximum leakage rate of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). Additionally, this cartridge has a high switching frequency capability of up to 15,000 cycles per hour and includes interchangeable coils compatible with other Sun Series 1 solenoid products. The valve's cavity designation is T-61A and includes various coil termination and voltage options with available surge protection. Coils can achieve protection ratings up to IP69K depending on configuration choices. The product weighs approximately .60 lb (.30 kg) and requires an installation torque of 30\u201335 lbf ft (41\u201347 Nm).

This solenoid-operated 6-way, 2-position cartridge is a direct-acting, balanced spool valve. The typical use for this valve is to select between two separate circuits. The de-energized condition connects P and T to the first circuit and when energized connects P and T to the second circuit.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
