The Sun Hydraulics DNDAXTN924N (DNDAXTN924N) is a solenoid-operated 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is engineered for high performance, with a fatigue-rated solenoid tube assembly that can handle up to 5000 psi (350 bar). It operates without the need for minimum hydraulic pressure and offers several manual override options, although compatibility with weatherized coils is limited. The D and L manual controls include a detent mechanism intended for temporary actuation, with an expected mechanical life of about 7,000 cycles. The valve's EPDM seals are suitable for systems using phosphate ester fluids but are incompatible with petroleum-based substances. Its wet armature design exposes the armature to working fluid and coil-generated heat, which may impact performance if the coil is energized over extended periods. A variety of coil termination and voltage configurations are available, some featuring surge protection. The high-efficiency solenoid provides strong spool actuation force per watt, ensuring dependable valve operation. Coils can be interchanged with other Sun Series 1 products and mounted bi-directionally on the tube. Coil connectors offer protection ratings up to IP69K. The cartridge incorporates Sun's floating style construction to reduce binding risks due to excessive torque or machining variations. It fits into cavity T-31A of Series 1 valves and has a capacity of 10 gpm (40 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with typical response times around 50 ms. Valve leakage at maximum conditions is minimal at 10 in\u00b3/min (160 cc/min). Manual override requires a force of approximately 5 lbs/1000 psi at Port 1 and features a stroke length of .10 inches (2.5 mm). The valve weighs .60 lb (.30 kg) and includes Viton seal kits for enhanced durability in demanding environments.

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.
