The Sun Hydraulics DNDATHN828 (DNDATHN828) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered for robust performance, the solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions without needing minimum hydraulic pressure. This valve features several manual override options, though it's important to note that manual override functionality is not compatible with weatherized coils. The D and L control models incorporate a detent mechanism in the manual override for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. This cartridge also accommodates EPDM seals suitable for systems using phosphate ester fluids; however, contact with petroleum-based substances should be avoided to prevent seal damage. The valve uses a wet armature design where working fluid surrounds the armature, potentially impacting performance if the coil remains energized over long periods due to heat exposure. Notably, fluids like water-glycol mixtures may degrade at these temperatures over time. A variety of coil termination and voltage options are available, including those with surge protection. The solenoid's magnetic design ensures high efficiency by delivering significant spool actuating force per watt expended, facilitating reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With cavity T-31A and Series 1 designation, this valve offers a capacity of 10 gpm (40 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It exhibits a typical response time of 50 ms and can handle up to 15,000 cycles per hour switching frequency. The valve's design minimizes internal part binding due to excessive installation torque or machining variations thanks to its floating style construction.

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.
