The Sun Hydraulics DNDATUV71299 (DNDATUV71299) is a solenoid-operated 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool valve does not require a minimum hydraulic pressure to operate, making it versatile for various applications. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The valve incorporates a wet armature design that allows the working fluid to surround the armature, which can be beneficial in dissipating heat generated by the coil but requires consideration of fluid compatibility over extended operation times. This model offers several manual override options, including versions without an override. Notably, the manual control assembly with D or L controls is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve is compatible with EPDM seals for use in systems containing phosphate ester fluids; however, these seals are not suitable for petroleum-based fluids. The DNDATUV71299 boasts efficient solenoid performance with its unique magnetic design, providing high spool actuating force per watt expended. This efficiency contributes to reliable valve shifting and extends the operational lifespan of the device. It supports various coil termination and voltage configurations, including surge protection options for enhanced adaptability to different system requirements. Designed with Sun's floating style construction, this cartridge minimizes internal part binding due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and response time typically around 50 ms, it suits applications demanding quick and consistent response times. Additionally, the interchangeable coils are compatible with other Sun Series 1 products, offering flexibility in system design and maintenance.

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.
