The Sun Hydraulics DNCADSN814N (DNCADSN814N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. With a capacity of 8 gpm/30 L/min and a maximum operating pressure of 5000 psi/350 bar, the DNCADSN814N is engineered to handle demanding applications. The valve's solenoid tube assembly is fatigue rated for high-pressure service up to 5000 psi (350 bar), ensuring durability and long-term performance. It operates effectively without any minimum hydraulic pressure requirement, offering versatility across various hydraulic systems. The DNCADSN814N utilizes EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based fluids as these can damage the seals. This model incorporates a wet armature design where the heat generated by the coil can affect fluid integrity if energized for extended periods. It supports various coil termination and voltage options, including configurations with surge protection. The solenoid's efficient magnetic design provides robust spool actuating force per watt expended, ensuring reliable valve operations. Additional features include interchangeable coils with other Sun Series 1 solenoid products, multiple coil connector options with ratings up to IP69K for enhanced environmental protection, and Sun's floating style construction which minimizes internal parts binding. The response time is typically around 50 ms, and the maximum valve leakage at 110 SUS (24 cSt) is maintained at about 10 in\u00b3/min at 3000 psi. This valve also supports a manual override feature and has been designed for easy installation with specific torque requirements detailed in its specifications.

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.
