The Sun Hydraulics DNDATRN512 (DNDATRN512) is a solenoid-operated 4-way, 2-position cartridge valve, specifically designed as a direct-acting, balanced spool directional valve. This model features a solenoid tube assembly that is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. It operates without requiring a minimum hydraulic pressure, making it versatile for various systems. The valve offers several manual override options, though these are not compatible with weatherized coils. Models with the D or L control have a detent mechanism in the manual override suitable for temporary actuation, with an estimated mechanical life of approximately 7,000 cycles. The DNDATRN512 incorporates EPDM seals for compatibility with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. It utilizes a wet armature design where working fluid surrounds the armature, which can be affected by prolonged coil energization due to heat exposure. The solenoid\u2019s efficient magnetic design provides high spool actuating force per watt expended, ensuring reliable valve shifting and high performance. This valve is built with Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It has a cavity size of T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), and it has a typical response time of 50 ms. The maximum valve leakage at 110 SUS (24 cSt) is specified at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). With interchangeable coils compatible with other Sun Series 1 products and coil connector options rated up to IP69K, the DNDATRN512 offers flexibility and robust environmental protection solutions for diverse hydraulic applications.

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.
