The Sun Hydraulics DNDAXNN4E12V (DNDAXNN4E12V) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically engineered for high-efficiency performance with its unique magnetic solenoid design, providing robust spool actuating force per watt of power used. It operates efficiently without requiring any minimum hydraulic pressure and is fatigue rated for service up to 5000 psi (350 bar). The valve incorporates a wet armature design which allows the working fluid to surround the armature, aiding in heat dissipation but also necessitating caution with fluid types that might degrade under prolonged heat exposure. The DNDAXNN4E12V offers flexibility in manual override options including configurations without manual overrides. However, it should be noted that manual override functions are incompatible with weatherized coils. The valve supports a variety of coil termination and voltage options, some of which offer surge protection and IP69K ratings for enhanced environmental resilience. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction on the tube. This cartridge valve has a capacity of 10 gpm (40 L/min) and features Sun's floating style construction to minimize binding issues due to installation variances. Its response time is typically around 50 ms, and it can handle a switching frequency of up to 15,000 cycles per hour. The maximum leakage at 110 SUS (24 cSt) is limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The DNDAXNN4E12V is also equipped with EPDM seals suitable for systems using phosphate ester fluids while avoiding petroleum-based substances which could damage the seals.

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.
