The Sun Hydraulics DNDAXRV548 (DNDAXRV548) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate without the need for minimum hydraulic pressure and features a solenoid tube assembly rated for fatigue at pressures up to 5000 psi (350 bar). The cartridge offers various manual override options, although models with manual overrides are not compatible with weatherized coils. For those equipped with D or L control, the manual override's detent mechanism is intended for temporary use with a mechanical life expectancy of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for systems using phosphate ester fluids; exposure to petroleum-based substances can damage these seals. It employs a wet armature design where the working fluid surrounds the armature, potentially affecting function over time if fluids like water-glycol mixtures are used and breakdown occurs due to heat from prolonged coil energization. The solenoid\u2019s magnetic design ensures high efficiency, providing substantial spool actuating force per watt expended and facilitating reliable valve shifting. A variety of coil termination and voltage options are available, some featuring surge protection. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. The coil connector options offer ratings up to IP69K for enhanced environmental protection. The valve's construction minimizes internal part binding issues due to installation torque or machining variations in cavity/cartridge fitting. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), this model features a typical response time of 50 ms and supports switching frequencies up to 15,000 cycles per hour. Installation requires a torque between 30-35 lbf-ft (41-47 Nm), while its hex size measures .78 inches (22.2 mm).

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.
