The Sun Hydraulics DNCADLV528 (DNCADLV528) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for robust hydraulic control. It features a direct-acting, balanced spool with a closed transition between positions to minimize oil loss during shifting. This characteristic is particularly beneficial in pilot control circuits where maintaining fluid integrity is crucial. The valve operates efficiently with a capacity based on port 3 as the inlet and port 1 as the tank, and while reverse flow is possible, it may not deliver the same performance and is generally not recommended. Engineered for durability and reliability, the solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar). It requires no minimum hydraulic pressure for operation, making it versatile across various applications. The DNCADLV528 utilizes EPDM seals when configured for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can degrade. Additionally, the DNCADLV528 employs a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods since some fluids can degrade under prolonged exposure to heat. The valve offers a range of coil termination and voltage options, including configurations with surge protection. Its innovative magnetic design enhances solenoid efficiency, ensuring high spool actuating force per watt expended which contributes to reliable valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Options for coil connectors are also available that provide environmental protection ratings up to IP69K. Moreover, Sun Hydraulics has incorporated its floating style construction into this model to reduce risks associated with internal parts binding due to installation errors or variations in cavity/cartridge machining.

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.
