The Sun Hydraulics DNDAXDN948 (DNDAXDN948) is a solenoid-operated 4-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. Engineered to withstand fatigue at 5000 psi (350 bar), this valve operates without the need for minimum hydraulic pressure, making it versatile for various applications. It features multiple manual override options; however, users should note that weatherized coils are incompatible with these overrides. The manual controls have a mechanical life expectancy of approximately 7,000 cycles, and cartridges with EPDM seals are specifically intended for systems using phosphate ester fluids. The wet armature design exposes the working fluid to coil-generated heat, which can lead to varnish formation in certain fluids like water-glycol mixtures if the coil remains energized for extended periods. This model offers a range of coil termination and voltage options, including those with surge protection. Its high-efficiency solenoid ensures reliable operation by delivering significant spool actuating force per watt consumed. The valve's design allows coil interchangeability with other Sun Series 1 solenoid products and can be installed in either orientation on the tube. Coil connectors provide protection up to IP69K ratings, enhancing environmental resilience through additional weatherized options. Utilizing Sun's floating style construction reduces the risk of internal binding from excessive installation torque or cavity machining variations. With a capacity of 10 gpm (40 L/min.), maximum operating pressure of 5000 psi (350 bar), and a typical response time of 50 ms, this cartridge is built for robust performance in demanding environments. The valve also features low leakage rates and high switching frequency capabilities, adding to its reliability in hydraulic systems.

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.
