The Sun Hydraulics DNCADJN748 (DNCADJN748) is a high-performance, solenoid-operated directional valve designed for precise hydraulic fluid control in various applications. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The valve is engineered to handle a flow capacity of up to 8 gpm/30 L/min, with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance variations. Constructed for durability and reliability under high pressures, the DNCADJN748's solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service. It operates without requiring a minimum hydraulic pressure, making it versatile for various system conditions. The valve employs EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Featuring a wet armature design, the DNCADJN748 allows the working fluid to surround the armature which can be significant if the coil remains energized over extended periods. This design consideration helps in managing heat but may affect fluid integrity in certain conditions. The valve also offers flexibility with numerous coil termination and voltage options including surge protection variants. The innovative magnetic design of the solenoid ensures high efficiency and robust spool actuating force per watt expended, promoting reliable valve operation. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. For enhanced environmental resilience, weatherized coils and kits are available. Sun Hydraulics has incorporated its floating style construction into this model to reduce potential internal parts binding due to installation torque or machining variations of cavity/cartridge. This feature along with its quick response time of typically 50 ms and maximum operating pressure capability makes DNCADJN748 an optimal choice for demanding hydraulic applications requiring precise control and reliability.

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.
