The Sun Hydraulics DNCADLN812N (DNCADLN812N) is a robust solenoid-operated, 4-way, 2-position cartridge valve designed for high-efficiency hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to potential performance issues. Constructed to handle a maximum operating pressure of 5000 psi (350 bar), the DNCADLN812N valve is fatigue rated for demanding applications. It requires no minimum hydraulic pressure for operation, making it versatile across various hydraulic systems. The cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, this valve incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is essential when the coil is energized for extended periods since some fluids may degrade under prolonged heat exposure. The solenoid's unique magnetic design ensures high efficiency and reliable valve shifting with minimal energy expenditure. For customization and adaptability in different environments, Sun Hydraulics offers a variety of coil termination and voltage options, including models with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and boast high environmental protection ratings up to IP69K. Furthermore, the DNCADLN812N benefits from Sun's floating style construction that reduces risks of internal parts binding due to installation torque or cavity/cartridge machining variations. With features like quick response times (approximately 50 ms), capacity up to 8 gpm (30 L/min), and manual override options, this valve stands out as a reliable choice for efficient directional control in hydraulic 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.
