The Sun Hydraulics DNCADLN528 (DNCADLN528) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing oil loss during shifts which is crucial in pilot control circuits. It functions optimally with port 3 as the inlet and port 1 as the tank, although it permits reverse flow under certain conditions. Engineered for durability, the DNCADLN528 features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for rigorous applications. The valve operates without needing a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The wet armature design of the DNCADLN528 means that the working fluid surrounds the armature. This design consideration is vital when the coil remains energized over extended periods since some fluids may degrade under prolonged exposure to heat. The valve offers an array of coil termination and voltage options, including models with surge protection and weatherized coils for enhanced environmental resilience. Additionally, its unique magnetic configuration contributes to a highly efficient solenoid that delivers strong spool actuating force per watt expended. This feature ensures reliable and consistent valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. The DNCADLN528 also benefits from Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining, thereby ensuring smoother operation and longer service life.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
