The Sun Hydraulics DNCADLN648 (DNCADLN648) 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 the loss of oil during shifting. This characteristic is especially beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. With a capacity of 8 gallons per minute and capable of handling maximum operating pressures up to 5000 psi (350 bar), the DNCADLN648 valve is robust and versatile for various hydraulic applications. The valve's design allows for reverse flow; however, optimal performance in this mode cannot be assured and is generally not recommended. The solenoid tube assembly of this model is fatigue rated for high-pressure service, ensuring durability and long-term reliability. This model also features a wet armature design where the working fluid surrounds the armature. Although this setup aids in compactness and heat absorption, it requires careful consideration of the fluid type used, as prolonged exposure to high temperatures can degrade certain fluids like water-glycol mixtures. The DNCADLN648 uses EPDM seals suitable for systems with phosphate ester fluids but should avoid contact with petroleum-based substances to prevent seal damage. Sun Hydraulics has equipped the DNCADLN648 with various coil termination and voltage options, enhancing its adaptability across different systems and environments. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, the valve incorporates Sun's floating style construction which reduces risks associated with internal parts binding due to installation variances or machining discrepancies. Overall, the Sun Hydraulics DNCADLN648 offers precise control and reliable operation in demanding hydraulic applications, making it a valuable component in advanced fluid power systems.

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.
