The Sun Hydraulics DNDYDXN228 (DNDYDXN228) is a solenoid-operated, 6-way, 2-position cartridge valve designed for direct-acting applications with a balanced spool. This valve is primarily employed to alternate 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. The solenoid tube assembly is engineered for fatigue resistance at pressures up to 5000 psi (350 bar). This direct-actuated valve requires no minimum hydraulic pressure for operation and features several manual override options, though these are not compatible with weatherized coils. The valve's wet armature design allows working fluid to surround the armature, which can influence performance if the coil remains energized for extended periods. A variety of coil termination and voltage options are available, including those with surge protection. The high-efficiency solenoid design ensures reliable valve shifting by providing significant spool actuating force per watt expended. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction. This cartridge incorporates Sun\u2019s floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It fits into a T-61A cavity and has a capacity of 5 gpm (20 L/min). The valve offers a maximum operating pressure of 5000 psi (350 bar) and typical response time of 50 ms. Designed for high-frequency switching up to 15,000 cycles per hour, it features low leakage rates at specified conditions and requires specific manual override force and stroke parameters. Viton seal kits are available for both cartridge and coil components.

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.
