The Sun Hydraulics DNDYXXV224 (DNDYXXV224) 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, and when energized, it shifts to connect P and T to the second circuit. This valve features a fatigue-rated solenoid tube assembly for 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. It operates directly without requiring minimum hydraulic pressure, making it versatile for various applications. Equipped with a wet armature design, the valve's working fluid surrounds the armature, which helps in heat dissipation but may affect certain fluids like water-glycol mixtures over time. The DNDYXXV224 offers several manual override options; however, these are not compatible with weatherized coils. The solenoid's magnetic design provides high efficiency and reliable shifting with minimal power consumption. Interchangeable coils within Sun's Series 1 products allow flexibility in coil orientation and termination options up to IP69K ratings. This cartridge employs Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. With a capacity of 5 gpm (20 L/min), it supports high-frequency switching up to 15,000 cycles per hour and exhibits a typical response time of 50 ms. The valve has a maximum leakage rate of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar) and requires an installation torque between 30-35 lbf ft (41-47 Nm). It includes Viton seal kits for both cartridge and coil components, ensuring compatibility with various operating environments.

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.
