The Sun Hydraulics DNDAXNN848 (DNDAXNN848) 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 suitable for pressures up to 5000 psi (350 bar). It operates without requiring any minimum hydraulic pressure, making it versatile for various applications. The valve offers several manual override options, although it's important to note that manual override functionality is not compatible with weatherized coils. For models with the D or L control, the detent mechanism in the manual override is intended for temporary actuation and has an approximate mechanical life of 7,000 cycles. This cartridge valve uses EPDM seals specifically designed for phosphate ester fluid systems; exposure to petroleum-based fluids will damage these seals. The wet armature design allows the working fluid to surround the armature, which can be affected by prolonged coil energization due to heat exposure. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade over time under high temperatures. The valve's solenoid features a unique magnetic design providing high efficiency and reliable spool actuation force per watt expended. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted in either direction, with connector options rated up to IP69K available for enhanced environmental protection. The Sun floating style construction minimizes internal part binding risks due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a response time typically around 50 ms, this valve supports switching frequencies up to 15,000 cycles/hour. It includes specific installation requirements such as a torque range of 30-35 lbf ft (41-47 Nm) and utilizes Viton seal kits for maintenance needs.

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.
