The Sun Hydraulics DNDAXRN71299 (DNDAXRN71299) is a solenoid-operated 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. It is engineered for high performance with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). This valve operates without requiring any minimum hydraulic pressure, making it versatile for various applications. A notable feature includes multiple manual override options, though these are not compatible with weatherized coils. The manual control assemblies have a mechanical life expectancy of about 7,000 cycles and require specific force and stroke for operation. This cartridge is designed with EPDM seals suitable for phosphate ester fluid systems but should not be exposed to petroleum-based fluids due to potential seal damage. The valve employs a wet armature design that allows the working fluid to cool the coil, although prolonged energization might affect certain fluids like water-glycol mixtures. It offers various coil termination and voltage configurations, many with surge protection, ensuring adaptability across different system requirements. The solenoid's magnetic design enhances efficiency by maximizing spool actuating force per Watt expended, ensuring reliable operation. Interchangeability of coils with other Sun Series 1 products provides flexibility in installation direction. For environmental resilience, coil connector options are available up to IP69K ratings. The floating style construction minimizes internal binding risks due to installation torque or cavity-cartridge machining variations. With a capacity of 10 gpm (40 L/min) and maximum leakage at 110 SUS (24 cSt) capped at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this valve is reliable under rigorous conditions. Its compact size facilitates integration into various hydraulic systems while maintaining operational integrity across up to 15,000 cycles per hour switching frequency.

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.
