The Sun Hydraulics DNDATSV824 (DNDATSV824) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct acting and balanced spool directional control. It features a solenoid tube assembly that is fatigue-rated for up to 5000 psi (350 bar) service, ensuring durability and reliability in high-pressure applications. This valve does not require a minimum hydraulic pressure for operation, making it versatile for various systems. Several manual override options are available, although compatibility with weatherized coils should be noted. For models with the D or L control, the detent mechanism in the manual override is intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The DNDATSV824 incorporates EPDM seals suitable for systems using phosphate ester fluids but cautions against exposure to petroleum-based fluids which can damage the seals. Its wet armature design allows working fluid to surround the armature and absorb heat from the coil, which is important to consider during prolonged coil energization as certain fluids may degrade over time. This model supports a wide range of coil termination and voltage options, with additional features like surge protection available. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction. The cartridge design minimizes internal part binding due to excessive installation torque or machining variations thanks to Sun's floating style construction. It fits into a T-31A cavity and is capable of handling a flow capacity of up to 10 gpm (40 L/min). With quick response times typically around 50 ms and low maximum valve leakage, this valve offers reliable performance in demanding applications where switching frequency can reach up to 15,000 cycles per hour.

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.
