The Sun Hydraulics DNDAXCV71299 (DNDAXCV71299) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This high-performance valve is fatigue-rated for service up to 5000 psi (350 bar) and does not require a minimum hydraulic pressure for operation. It features a wet armature design, which allows the working fluid to surround the armature and manage heat generated by the coil. This makes it crucial to consider fluid compatibility, as some fluids may degrade at elevated temperatures over time. The DNDAXCV71299 offers several manual override options, although it's important to note that these are incompatible with weatherized coils. The manual override mechanism, particularly in models with D or L control, is intended for temporary actuation and has an estimated mechanical life of approximately 7,000 cycles. The valve's solenoid exhibits a unique magnetic design that maximizes efficiency by providing high spool actuating force relative to power consumption. This model incorporates Sun's floating style construction to minimize binding risks due to installation torque or machining variations. It supports a wide array of coil termination and voltage options, including those with surge protection, while coil connectors can achieve ratings up to IP69K for enhanced environmental protection. With a capacity of 10 gpm (40 L/min), this valve operates efficiently within its specified parameters and maintains low leakage rates at maximum operating pressures. The DNDAXCV71299 is compatible with various seal kits for different fluid applications, such as Viton seals for systems using phosphate ester fluids. Its robust design and versatility make it suitable for demanding hydraulic applications where reliability and precision are essential.

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.
