The Sun Hydraulics DNDAXHN824 (DNDAXHN824) is a solenoid-operated 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. Engineered for high performance, the solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring reliability under demanding conditions. This valve operates without the need for minimum hydraulic pressure, making it versatile in various applications. It includes multiple manual override options, although the manual override is not compatible with weatherized coils. For models with D or L control, the detent mechanism in the manual override is designed for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The cartridge is compatible with EPDM seals for systems utilizing phosphate ester fluids but should avoid petroleum-based fluids to prevent seal damage. The wet armature design exposes working fluid to coil-generated heat, which may affect certain fluids like water-glycol mixtures over time. The solenoid's magnetic design offers high efficiency by maximizing spool actuating force per watt expended, ensuring dependable valve shifting. With interchangeable coils from Sun Series 1 solenoid products and mounting flexibility in either direction, this model accommodates various coil termination and voltage options, including those with surge protection. Coil connector options are rated up to IP69K for enhanced environmental protection. The valve employs Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. Key specifications include a cavity size of T-31A, a series designation of 1, a capacity of 10 gpm (40 L/min), and a response time of approximately 50 ms. It has a maximum leakage rate at specified viscosity and pressure of 10 in\u00b3/min (160 cc/min) and supports switching frequencies up to 15,000 cycles per hour. The valve installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm).

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.
