The Sun Hydraulics DNDAXSV248 (DNDAXSV248) 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 capable of withstanding service pressures up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. This valve operates without the need for minimum hydraulic pressure, offering versatility in various systems. Users can select from multiple manual override options, although these are not compatible with weatherized coils. The D, L, and T manual control assemblies have a mechanical life expectancy of approximately 7,000 cycles and are intended for temporary actuation. The valve incorporates EPDM seals specifically for systems utilizing phosphate ester fluids; however, these seals should not be exposed to petroleum-based fluids as they can cause damage. The wet armature design allows the working fluid to cool the armature but requires consideration of fluid types, as some may degrade under prolonged exposure to heat generated by the coil. With robust coil termination and voltage options available\u2014including surge protection\u2014this high-efficiency solenoid provides reliable valve shifting due to its unique magnetic design that maximizes spool actuating force per watt expended. Compatible with other Sun Series 1 solenoid products, the coils can be mounted in either direction on the tube. The cartridge utilizes Sun's floating style construction to reduce potential binding from excessive torque or machining variations. Key specifications include 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), and a switching frequency up to 15,000 cycles/hr. The valve is designed for easy installation with a hex size of 7/8 inches and recommended torque between 30-35 lbf ft (41-47 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.
