The Sun Hydraulics DNDATDN612N (DNDATDN612N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve is engineered for high performance, featuring a solenoid tube assembly that is fatigue-rated for up to 5000 psi (350 bar) service, making it suitable for demanding hydraulic applications. It operates without requiring minimum hydraulic pressure, ensuring reliable function in various conditions. The valve offers several manual override options; however, these are not compatible with weatherized coils. The detent mechanism in the manual override is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The DNDATDN612N is constructed with EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. It employs a wet armature design where the working fluid surrounds the armature, which can be affected by prolonged coil energization leading to potential fluid breakdown in certain mixtures like water-glycol. This model supports a wide range of coil termination and voltage options with or without surge protection and boasts an efficient solenoid magnetic design that maximizes spool actuating force per watt. Coils are interchangeable with other Sun Series 1 products and offer mounting flexibility. The valve also incorporates Sun's floating style construction to mitigate internal binding risks due to excessive installation torque or machining variations. Key specifications include a cavity size of T-31A, series 1 capacity of 10 gpm (40 L/min), response time of approximately 50 ms, maximum leakage at standard viscosity of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and capability for switching frequencies up to 15,000 cycles/hr. The valve features a manual override stroke of .10 inches (2.5 mm) and requires specific force requirements depending on port pressure conditions.

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.
