The Sun Hydraulics DNDAXUN248 (DNDAXUN248) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. Engineered for versatility and durability, this valve operates without the need for minimum hydraulic pressure and is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. It incorporates a wet armature design that allows the working fluid to surround the armature, which aids in heat dissipation but requires careful selection of fluids to avoid varnish formation during prolonged coil energization. Several manual override options are available, although they are not compatible with weatherized coils. The manual override mechanism's detent feature on models with D or L control is intended for temporary actuation and offers a mechanical life expectancy of approximately 7,000 cycles. The cartridge's robust construction includes Sun's floating style design to minimize internal component binding due to installation torque or machining variations. The DNDAXUN248 supports a variety of coil termination and voltage options, some equipped with surge protection. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction. Coil connectors can achieve ratings up to IP69K for enhanced environmental protection. The valve boasts high efficiency due to its unique magnetic solenoid design, providing reliable shifting with minimal energy consumption. This cartridge fits into a T-31A cavity and has a capacity of up to 10 gpm (40 L/min). It features rapid response times typically around 50 ms and can handle switching frequencies up to 15,000 cycles per hour. Maximum valve leakage is rated at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), ensuring efficient performance across various operational conditions.

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.
