The Sun Hydraulics DNDYLXN528 (DNDYLXN528) is a solenoid-operated 6-way, 2-position cartridge valve designed for seamless circuit selection between two separate systems. This direct-acting, balanced spool valve functions without the need for minimum hydraulic pressure, making it versatile and efficient in various applications. In its de-energized state, it connects ports P and T to the first circuit, while energizing the solenoid redirects these connections to the second circuit. The valve is built with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The design incorporates a wet armature system where the working fluid surrounds the armature, which may impact performance if fluids like water-glycol mixtures are used over extended periods due to heat exposure from the coil. The high-efficiency solenoid offers substantial spool actuating force per watt, promoting dependable valve shifting. The DNDYLXN528 features several manual override options with a mechanical life expectancy of approximately 7,000 cycles; however, manual override is not compatible with weatherized coils. This valve supports various coil termination and voltage options, including those with surge protection. Coils can be interchanged with other Sun Series 1 products and mounted in either direction on the tube. Optional coil connectors provide ratings up to IP69K for enhanced environmental protection. The floating style construction minimizes internal binding risks from excessive installation torque or machining variations. With a cavity size of T-61A and a capacity of 5 gpm (20 L/min), this model exhibits minimal leakage at maximum operating pressures and offers rapid response times typical at 50 ms. Its robust design allows for switching frequencies up to 15,000 cycles per hour, making it suitable for demanding hydraulic applications requiring reliable performance and adaptability.

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.
