The Sun Hydraulics DNDYXXN228 (DNDYXXN228) 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, balanced spool valve does not require any minimum hydraulic pressure for operation and is fatigue rated for 5000 psi (350 bar) service. It features a wet armature design where the working fluid surrounds the armature, which could affect performance if exposed to high temperatures over long periods. The valve's mechanical components include several manual override options, with a detent mechanism available on models equipped with D or L controls for temporary actuation. The manual override has a mechanical life expectancy of around 7,000 cycles. The DNDYXXN228 incorporates Sun's floating style construction to minimize binding due to installation torque or machining variations. It offers a capacity of 5 gpm (20 L/min) and supports a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 50 milliseconds, with maximum valve leakage rated at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). This cartridge can handle switching frequencies up to 15,000 cycles per hour. Coil options are versatile with various termination and voltage configurations available, including weather-resistant versions rated up to IP69K for enhanced environmental protection. The solenoid\u2019s magnetic design ensures high efficiency and reliable valve shifting by optimizing spool actuating force per watt expended. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube.

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.
