The Sun Hydraulics DNDAXZV72499 (DNDAXZV72499) is a solenoid-operated 4-way, 2-position cartridge valve designed for high-efficiency and reliable directional control in hydraulic systems. This direct-acting, balanced spool valve operates without the need for minimum hydraulic pressure and features a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar). It incorporates a wet armature design, which allows the working fluid to surround the armature, exposing it to heat from the coil\u2014a consideration for long-term coil energization as certain fluids may degrade over time. The valve offers multiple manual override options, including models with temporary actuation detents; however, these are not compatible with weatherized coils. The DNDAXZV72499 supports a variety of coil termination and voltage configurations, some with surge protection, and can be equipped with interchangeable coils from other Sun Series 1 products. With a capacity of 10 gpm (40 L/min) and response time typically around 50 ms, it is suitable for applications requiring precise flow control and fast switching frequency up to 15,000 cycles per hour. Designed with Sun's floating style construction, this cartridge minimizes internal binding risks due to installation torque or machining variations. It also includes Viton seal kits for both cartridge (990431006) and coil (990770006), ensuring compatibility with phosphate ester fluids while avoiding petroleum-based substances that could damage seals. Offering IP69K-rated coil connector options and additional weatherized solutions, this model is engineered for robust performance in demanding 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.
