The Sun Hydraulics DNDATXN298 (DNDATXN298) is a solenoid-operated, 4-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Engineered for high performance, this valve is fatigue-rated for service up to 5000 psi (350 bar) and does not require any minimum hydraulic pressure for operation. It features a wet armature design, where the working fluid surrounds the armature, aiding in dissipating heat generated by the coil. The valve supports various manual override options; however, note that manual overrides are not compatible with weatherized coils. Models with D or L control include a detent mechanism intended for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. This cartridge is suitable for systems using phosphate ester fluids when equipped with EPDM seals but should be kept away from petroleum-based fluids to prevent seal damage. It offers flexibility with multiple coil termination and voltage options, some including surge protection. The solenoid's magnetic design ensures high efficiency by delivering significant spool actuating force per watt expended. Coils are interchangeable within the Sun Series 1 solenoid products and can be mounted in either direction. The DNDATXN298 incorporates Sun's floating style construction to reduce the risk of internal binding due to installation torque or cavity-cartridge machining variations. It fits into a T-31A cavity and has a capacity of 10 gpm (40 L/min). The valve's response time is typically around 50 ms with maximum leakage at 110 SUS (24 cSt) being 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports a switching frequency of up to 15,000 cycles per hour and requires a manual override force of approximately 5 lbs/1000 psi.

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.
