The Sun Hydraulics DNDATSN824 (DNDATSN824) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring high reliability in demanding applications. It operates without requiring a minimum hydraulic pressure, making it versatile for various systems. The valve offers multiple manual override options, although these are not compatible with weatherized coils. Notably, models with D or L control have a detent mechanism suitable for temporary actuation and boast a mechanical life expectancy of approximately 7,000 cycles. This cartridge valve includes EPDM seals specifically designed for systems using phosphate ester fluids; however, exposure to petroleum-based substances will damage the seals. Utilizing a wet armature design, the working fluid surrounds the armature and absorbs heat from the coil, which can affect fluid stability over prolonged periods of coil energization. A particular concern is with water-glycol mixtures that may degrade at high temperatures. The solenoid's magnetic design maximizes efficiency by providing high spool actuating force per watt expended, ensuring reliable valve shifting. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be installed in either direction on the tube. Coil connector options offer protection ratings up to IP69K, enhancing environmental resilience. With a cavity size of T-31A and series designation of 1, this valve has a capacity of 10 gpm (40 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). It responds quickly with typical response times around 50 ms and maintains low leakage rates under specified conditions. The valve's construction minimizes internal binding risks due to installation torque or machining variations, further contributing to its reliability and performance in hydraulic systems.

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.
