The Sun Hydraulics DNDATRV724 (DNDATRV724) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve does not require minimum hydraulic pressure for operation, making it versatile for various applications. It features a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The cartridge offers several manual override options, with specific models incorporating a detent mechanism for temporary actuation. However, note that manual override functionality is incompatible with weatherized coils. The valve is equipped with EPDM seals suitable for phosphate ester fluids while being susceptible to damage from petroleum-based substances. Its wet armature design allows the working fluid to cool the armature but may lead to varnish formation in certain fluids over time when the coil is energized continuously. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per Watt expended, ensuring reliable valve shifting even in demanding environments. Multiple coil termination and voltage options are available, including those with surge protection and weatherized variants offering environmental protection up to IP69K ratings. Notably, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. The DNDATRV724 incorporates Sun's floating style construction to minimize internal part binding due to excessive torque or machining variations during installation. With a capacity of 10 gpm (40 L/min) and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this valve supports high-frequency switching up to 15,000 cycles per hour, making it suitable for applications requiring rapid response times and consistent performance.

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.
