The Sun Hydraulics DNDAXEN824 (DNDAXEN824) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. Engineered for robust performance, this valve is fatigue-rated for service up to 5000 psi (350 bar) and does not require a minimum hydraulic pressure for operation. It offers several manual override options, although weatherized coils are incompatible with manual overrides. The D, L, and T control models include a detent mechanism for temporary actuation with an estimated mechanical life of around 7,000 cycles. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended due to potential damage from petroleum-based products. The valve's wet armature design allows the working fluid to cool the coil; however, prolonged energization could lead to fluid breakdown in water-glycol mixtures. This model provides flexibility with various coil termination and voltage options and boasts an efficient magnetic design for high spool actuating force per watt. Coils are interchangeable within Sun Series 1 products and can be mounted bidirectionally on the tube. The valve incorporates Sun\u2019s floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits cavity T-31A and has a capacity of 10 gpm (40 L/min). With a typical response time of 50 ms and maximum leakage at 110 SUS of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), it supports switching frequencies up to 15,000 cycles/hr. Installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), with a hex size of .78 in (22.2 mm). The model weighs .60 lb (.30 kg) and comes with Viton seal kits available separately for both the cartridge and coil components.

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.
