The Sun Hydraulics DNDAXRN4E12V (DNDAXRN4E12V) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. Engineered for high performance, this valve accommodates a maximum operating pressure of 5000 psi (350 bar) and supports a flow capacity of 10 gpm (40 L/min). The solenoid tube assembly is fatigue-rated for durability under high-pressure service conditions. This direct-actuated valve requires no minimum hydraulic pressure for operation, making it versatile in various applications. It includes multiple manual override options, though models with weatherized coils are not compatible with manual overrides. For models equipped with D or L control, the detent mechanism in the manual override is designed for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The valve employs a wet armature design where working fluid surrounds the armature, which can influence performance if the coil is energized for extended periods. Specifically, fluids like water-glycol mixtures may degrade over time due to heat exposure from the coil. The solenoid's magnetic design ensures high efficiency by delivering substantial spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 products and offer installation flexibility by mounting in either direction on the tube. Additional features include coil connector options rated up to IP69K for enhanced environmental protection and interchangeability with weatherized coils and kits for comprehensive protection against environmental elements. The construction incorporates Sun's floating style to reduce potential binding from excessive installation torque or machining variations in cavity/cartridge interfaces. The valve\u2019s technical specifications include a response time of approximately 50 ms and a switching frequency capability of up to 15,000 cycles per hour, making it suitable for demanding operational environments.

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.
