The Sun Hydraulics DNDATRN812N (DNDATRN812N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional flow control. This versatile valve is engineered for high-performance applications, offering a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). It operates without the need for minimum hydraulic pressure, making it suitable for various hydraulic systems. The valve features multiple manual override options, although the manual override functionality is not compatible with weatherized coils. The detent mechanism in the D or L control manual override is intended for temporary actuation, with an estimated mechanical life of about 7,000 cycles. This valve incorporates a wet armature design that allows working fluid to surround the armature, which helps dissipate heat generated by the coil. However, prolonged energization can affect certain fluids like water-glycol mixtures due to potential varnish formation. It offers numerous coil termination and voltage options with or without surge protection and provides high efficiency due to its unique magnetic design. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction. The DNDATRN812N uses Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations. It fits into a T-31A cavity and boasts a capacity of 10 gpm (40 L/min). With a response time of approximately 50 ms and a maximum switching frequency of 15,000 cycles per hour, this valve ensures reliable performance. Its maximum leakage at 110 SUS (24 cSt) is limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), making it an efficient choice for precise directional flow control in demanding environments.

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.
