The Sun Hydraulics DNDAXUV72419 (DNDAXUV72419) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is capable of handling a maximum operating pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly for high-pressure service. The valve operates efficiently without the need for minimum hydraulic pressure, making it versatile for various applications. It offers multiple manual override options, though certain models with manual controls like D or L are intended for temporary actuation only. The mechanical life expectancy of these controls is approximately 7,000 cycles. The DNDAXUV72419 employs a wet armature design where the working fluid surrounds the armature, which can be affected by heat from prolonged coil energization. This is particularly important when using fluids like water-glycol mixtures that may degrade under such conditions. A wide range of coil termination and voltage options are available to suit different requirements, with some configurations offering surge protection and IP69K-rated coil connectors for enhanced environmental resilience. With an impressive switching frequency of up to 15,000 cycles per hour and a typical response time of 50 ms, this valve ensures reliable performance in demanding applications. The design incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. For systems using phosphate ester fluids, EPDM seals are recommended to prevent damage from petroleum-based substances. The cartridge has a capacity of 10 gpm (40 L/min) and maintains maximum leakage at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve's compact size includes a solenoid tube diameter of .75 inches (19 mm) and a hex size of .78 inches (22.2 mm), with an installation torque specification between 30-35 lbf ft (41-47 Nm).

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.
