The Sun Hydraulics DNDATJN512 (DNDATJN512) is a solenoid-operated 4-way, 2-position cartridge valve, featuring a direct-acting, balanced spool directional design. This valve is engineered for high-pressure applications with its solenoid tube assembly rated for up to 5000 psi (350 bar), ensuring durability and reliable performance. It operates directly without the need for minimum hydraulic pressure, making it versatile in various hydraulic systems. The product offers multiple manual override options, though the weatherized coil models are not compatible with this feature. For models with D or L control, the manual override's detent mechanism supports temporary actuation with a life expectancy of approximately 7,000 cycles. Designed using a wet armature system, this valve allows the working fluid to surround the armature and absorb heat from the coil. Users should be cautious of fluid breakdown in high-temperature scenarios, especially when using water-glycol mixtures that may form varnishes affecting functionality over time. The valve supports various coil termination and voltage options, enhancing its adaptability to different system requirements. It features a unique magnetic design that delivers high efficiency by maximizing spool actuating force while minimizing energy consumption. The cartridge follows Sun's floating style construction to reduce internal binding risks due to installation torque or cavity machining variations. With a capacity of 10 gpm (40 L/min) and typical response time of 50 ms, it provides efficient flow control under demanding conditions. Its maximum leakage rate is maintained at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), ensuring minimal fluid loss during operation. The DNDATJN512 is compatible with interchangeable coils from Sun Series 1 solenoid products and can be installed in any orientation on the tube for added convenience and flexibility in hydraulic systems design and maintenance.

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.
