The Sun Hydraulics DNCADJN814N (DNCADJN814N) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid control in various applications. This direct-acting, balanced spool directional valve ensures smooth transitions between positions with a closed transition that minimizes oil loss during shifting, crucial for maintaining efficiency in pilot control circuits. The valve operates efficiently with port 3 as the inlet and port 1 as the tank, supporting a flow capacity of 8 gpm (30 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Although it allows reverse flow, optimal performance in this mode is not assured. The DNCADJN814N features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi service and does not require minimum hydraulic pressure for operation, enhancing its versatility across various hydraulic systems. Equipped with EPDM seals, this valve is specifically configured for use with phosphate ester fluids; however, it is sensitive to exposure to petroleum-based fluids which may damage the seals. The wet armature design of the valve means that the working fluid surrounds the armature which could be subject to heat if the coil remains energized over extended periods. This factor needs consideration especially when using water-glycol mixtures that might degrade under heat. For customization and adaptability to different system requirements, Sun Hydraulics offers a variety of coil termination and voltage options for this model, including options with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With additional features like an IP69K rating available for certain coil connector options and weatherized coils for enhanced environmental protection, this valve stands out as a reliable choice for demanding hydraulic applications while ensuring minimal internal parts binding through its floating style construction.

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.
