The Sun Hydraulics DNDAXXV524 (DNDAXXV524) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a fatigue-rated solenoid tube assembly suitable for service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding hydraulic applications. This valve operates directly without requiring minimum hydraulic pressure, making it versatile for various systems. Notable are its manual override options, including models without manual override, with the D or L control offering temporary actuation through a detent mechanism. The manual control assembly has an estimated mechanical life of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for phosphate ester fluid systems but is incompatible with petroleum-based fluids. Its wet armature design allows working fluid exposure to coil-generated heat, which can affect fluid stability over time in certain mixtures like water-glycol. The solenoid's magnetic design offers high efficiency and reliable spool shifting with significant actuating force per watt expended. A variety of coil termination and voltage configurations are available, with options for surge protection and weatherized coils providing environmental resilience up to IP69K ratings. The interchangeable coils align with other Sun Series 1 solenoid products. The floating style construction minimizes internal binding risks due to torque or machining variations. Key specifications include a T31A cavity size, Series 1 classification, a capacity of 10 gpm (40 L/min), response time typically at 50 ms, maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar), and switching frequency up to 15,000 cycles/hr. Installation requires a torque between 30-35 lbf-ft (41-47 Nm), and the model weighs approximately .60 lb (.30 kg).

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.
