The Sun Hydraulics DNDAXLV71299 (DNDAXLV71299) is a solenoid-operated 4-way, 2-position cartridge valve designed for high-performance directional control in hydraulic systems. This direct-acting, balanced spool valve operates without the need for minimum hydraulic pressure, ensuring reliability in various applications. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), making it suitable for demanding environments. A notable feature of this valve is its manual override options, which include configurations with no manual override or temporary actuation detents, although these are not compatible with weatherized coils. The valve's design incorporates a wet armature system, where the working fluid surrounds the armature, exposing it to coil-generated heat\u2014an important consideration for long-term coil energization and fluid compatibility. This cartridge offers versatility with a variety of coil termination and voltage options, including surge protection capabilities. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 products and can be mounted bidirectionally on the tube. Additional weatherized coils and kits are available to ensure environmental protection with connector options rated up to IP69K. The DNDAXLV71299 model features Sun's floating style construction to minimize binding risks due to installation torque or machining variations. It fits into a T31A cavity and supports a flow capacity of 10 gpm (40 L/min), with maximum operating pressures reaching 5000 psi (350 bar). Typical response time is around 50 ms, and the valve can handle switching frequencies up to 15,000 cycles per hour. For maintenance or replacement needs, Viton seal kits are available for both cartridge and coil assemblies.

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.
