The Sun Hydraulics DNCADJV528 (DNCADJV528) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting. This characteristic is especially beneficial in pilot control circuits where maintaining fluid integrity is critical. The valve operates with a capacity based on port 3 as the inlet and port 1 as the tank, and while reverse flow is possible, it is not recommended due to potential performance variations. Constructed to handle demanding applications, the DNCADJV528 can withstand up to 5000 psi (350 bar) and does not require a minimum hydraulic pressure for operation. It includes EPDM seals suited for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. The design incorporates a wet armature setup where the working fluid surrounds the armature\u2014this could lead to fluid breakdown in prolonged energized states due to heat exposure from the coil. For versatility in installation and use, this model offers various coil termination and voltage options, including configurations with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, connector options for the coils are rated up to IP69K for enhanced environmental protection. The DNCADJV528 also benefits from Sun\u2019s floating style construction which helps reduce internal parts binding that might occur due to excessive installation torque or cavity/cartridge machining discrepancies. With features like rapid response times (typical 50 ms), maximum operating pressures of 5000 psi (350 bar), and capacities up to 8 gpm (30 L/min), this valve is engineered for robust performance and reliability in various hydraulic applications.

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.
