The Sun Hydraulics DNDAXEV72499 (DNDAXEV72499) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered for high-performance applications, this valve features a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar) service pressure. It operates without the need for minimum hydraulic pressure and offers several manual override options, although these are not compatible with weatherized coils. The manual override mechanism is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This valve is suitable for use in systems utilizing phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to cool the armature but may lead to varnish formation in certain fluids if the coil remains energized over extended periods. This model provides various coil termination and voltage options, some with surge protection, ensuring reliable performance across different setups. The DNDAXEV72499 features Sun's unique magnetic design that enhances solenoid efficiency by delivering high spool actuating force per watt expended. Coils are interchangeable within the Sun Series 1 range and can be mounted bidirectionally on the tube. It offers coil connector options rated up to IP69K for robust environmental protection. The valve incorporates Sun's floating style construction to minimize internal binding risks due to installation or machining variations. With a flow capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge valve delivers reliable performance with a typical response time of 50 ms and minimal leakage at standard viscosity levels. The switching frequency reaches up to 15,000 cycles per hour, making it suitable for demanding applications requiring frequent actuation.

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.
