The Sun Hydraulics DNDAXUV748 (DNDAXUV748) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. The valve is engineered to withstand fatigue with a solenoid tube assembly rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. Notably, this valve does not require any minimum hydraulic pressure for operation, allowing flexibility in various system designs. It offers several manual override options, although models with manual override are not compatible with weatherized coils. The D and L control models feature a detent mechanism intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This cartridge employs EPDM seals specifically designed for systems utilizing phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to surround the armature, which can affect fluid stability if the coil is energized over long durations, particularly in water-glycol mixtures. The valve supports various coil termination and voltage configurations, enhancing versatility across different setups. Its unique magnetic design ensures high efficiency by maximizing spool actuating force per watt expended, contributing to reliable performance. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, connector options provide protection ratings up to IP69K. The DNDAXUV748 incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve features a typical response time of 50 ms and supports switching frequencies up to 15,000 cycles per hour.

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.
