The Sun Hydraulics DNDAXJV298 (DNDAXJV298) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. This valve operates without requiring a minimum hydraulic pressure and offers various manual override options, although weatherized coils are not compatible with manual overrides. Models with D or L control include a detent mechanism for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. The valve is compatible with EPDM seals for systems using phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. This valve employs a wet armature design that allows the working fluid to surround the armature and absorb heat from the coil, which is crucial for prolonged coil energization periods. Certain fluids like water-glycol mixtures may degrade over time due to this heat exposure. The solenoid's magnetic design enhances efficiency by delivering high spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable within the Sun Series 1 range and can be mounted in either direction on the tube. Coil connector options support ratings up to IP69K for enhanced environmental protection. The DNDAXJV298 incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations in cavity-cartridge interfaces. It fits into T31A cavities and has a capacity of 10 gpm (40 L/min). The maximum operating pressure is set at 5000 psi (350 bar), with typical response times around 50 ms and leakage rates at maximum conditions of approximately 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). With switching frequencies up to 15,000 cycles per hour, this valve ensures robust performance across various 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.
