The Sun Hydraulics DNDYLXN71219 (DNDYLXN71219) is a solenoid-operated, 6-way, 2-position cartridge valve designed for direct-acting and balanced spool applications. This versatile valve is primarily utilized for selecting between two separate circuits, with the de-energized state connecting P and T to the first circuit and the energized state connecting P and T to the second circuit. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Notably, this valve requires no minimum hydraulic pressure for operation, making it highly adaptable across various systems. Equipped with manual override options including D, L, and T controls, the valve provides temporary actuation capabilities with a mechanical life expectancy of approximately 7,000 cycles. However, it should be noted that manual override functionality is not compatible with weatherized coils. The wet armature design allows working fluid to surround the armature, which can influence performance if coils are energized for extended periods\u2014especially in fluids like water-glycol mixtures that may degrade at high temperatures. The DNDYLXN71219 offers a variety of coil termination and voltage options, some with surge protection. Its unique magnetic design ensures high efficiency by delivering significant spool actuating force per watt consumed. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental protection needs, coil connector options are available with ratings up to IP69K. This cartridge employs Sun's floating style construction to minimize risks of internal part binding due to excessive installation torque or machining variations. It fits into a T-61A cavity from Series 1 and has a capacity of 5 gpm (20 L/min). The valve's response time typically measures around 50 ms with a maximum leakage rate of 5 in/min at 3000 psi (80 cc/min at 210 bar).

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.
