The Sun Hydraulics DNDAXLN224N (DNDAXLN224N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar), ensuring robust performance without the need for minimum hydraulic pressure. The DNDAXLN224N offers several manual override options, although these are not compatible with weatherized coils. Notably, models with D or L controls incorporate a detent mechanism intended for temporary actuation and have an approximate mechanical life expectancy of 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are recommended; however, these seals can be damaged by petroleum-based fluids. The valve employs a wet armature design where the working fluid surrounds the armature, which can lead to fluid degradation under prolonged coil energization due to heat exposure. A variety of coil termination and voltage options are available to enhance operational flexibility and include surge protection features. The high-efficiency solenoid design ensures reliable valve shifting by delivering substantial spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 products and can be mounted bidirectionally on the tube. The DNDAXLN224N incorporates Sun's floating style construction to mitigate internal part binding caused by excessive installation torque or machining variations in cavity/cartridge interfaces. It accommodates a flow capacity of up to 10 gpm (40 L/min) and maintains maximum operational pressure at 5000 psi (350 bar). The typical response time is approximately 50 ms, and it supports a switching frequency of up to 15,000 cycles per hour. Additional specifications include a manual override force requirement of 5 lbs/1000 psi and a manual override stroke of .10 inches (2.5 mm).

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.
