The Sun Hydraulics DNDAXJN814 (DNDAXJN814) is a solenoid-operated, 4-way, 2-position cartridge valve known for its direct-acting, balanced spool directional capabilities. Designed for robust performance, this cartridge valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. It operates without the need for minimum hydraulic pressure and offers multiple manual override options, although manual override functionality is incompatible with weatherized coils. Notably, models with D or L control have a detent mechanism in the manual override intended for temporary actuation and boast a mechanical life expectancy of approximately 7,000 cycles. This valve incorporates EPDM seals specifically designed for systems using phosphate ester fluids; these seals are not compatible with petroleum-based fluids. Utilizing a wet armature design, the valve's working fluid surrounds the armature and is exposed to heat from the coil, which can affect fluid stability over time when energized continuously. The solenoid's magnetic design ensures high efficiency by providing significant spool actuating force per watt expended. The DNDAXJN814 model offers interchangeable coils that fit other Sun Series 1 solenoid products and can be mounted in either direction. Coil connector options provide ratings up to IP69K for enhanced environmental protection. The valve uses Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), this model delivers reliable performance with typical response times of 50 ms and minimal leakage under specified conditions. Its compact design includes specifications like a .75 in (19 mm) solenoid tube diameter and .60 lb (0.30 kg) weight, making it an efficient choice for various hydraulic applications.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges 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.
