The Sun Hydraulics DNCADLN748 (DNCADLN748) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a vital feature for pilot control circuits. Its design allows for port 3 to serve as the inlet and port 1 as the tank outlet. While reverse flow is possible through this configuration, optimal performance in this manner is not assured and generally not recommended. The DNCADLN748 valve is engineered to be fatigue rated for operations at pressures up to 5000 psi (350 bar), ensuring robust performance under demanding conditions. It operates without requiring a minimum hydraulic pressure, enhancing its usability across various applications. The valve's wet armature design exposes the working fluid to heat generated by the coil when energized over long periods. This could lead to breakdowns in certain fluids like water-glycol mixtures, potentially affecting cartridge functionality due to varnish formation. This model offers flexibility in coil terminations and voltage options, including configurations with or without surge protection. Its magnetic design enhances solenoid efficiency, providing high spool actuating force per watt expended for reliable valve shifting. The interchangeable coils with other Sun Series 1 solenoid products add versatility and ease of maintenance. Additionally, the DNCADLN748 incorporates Sun\u2019s floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. It supports a maximum flow capacity of 8 gpm (30 L/min) and can handle switching frequencies up to 15000 cycles per hour with a typical response time of 50 ms. With manual override options and various environmental protection enhancements available, this valve stands out as a dependable choice for diverse 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.
