The Sun Hydraulics DNDAXTN724 (DNDAXTN724) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This versatile valve is rated for fatigue service up to 5000 psi (350 bar), making it suitable for demanding applications without requiring a minimum hydraulic pressure for operation. The DNDAXTN724 features multiple manual override options, although these are not compatible with weatherized coils. Models with the D or L control offer a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. The valve employs a wet armature design that allows the working fluid to surround the armature, absorbing heat generated by the coil. While this design enhances efficiency and reliability by providing high spool actuating force per watt expended, it's important to consider fluid compatibility\u2014particularly with EPDM seals that are suitable only for phosphate ester fluids. The valve offers various coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. Engineered for high switching frequency up to 15,000 cycles per hour and featuring a typical response time of 50 ms, this cartridge is capable of handling capacities up to 10 gpm (40 L/min). Its floating style construction minimizes internal binding risks due to installation torque variations. With an installation torque range of 30-35 lbf ft (41-47 Nm) and compact dimensions\u2014including a solenoid tube diameter of .75 inches (19 mm)\u2014this valve is both robust and space-efficient. Additional coil connector options provide environmental protection ratings up to IP69K, ensuring adaptability across various operational 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.
