The Sun Hydraulics DNDATXN612N (DNDATXN612N) is a solenoid-operated, 4-way, 2-position cartridge valve known for its direct-acting, balanced spool directional capabilities. Designed to perform under high-stress conditions, the solenoid tube assembly of this valve is fatigue-rated for service pressures up to 5000 psi (350 bar). It operates without requiring any minimum hydraulic pressure, making it versatile for various applications. The valve offers several manual override options, although it's important to note that these are not compatible with weatherized coils. For models with the D or L control, the detent mechanism in the manual override is intended for temporary actuation and boasts a mechanical life expectancy of around 7,000 cycles. In terms of compatibility and efficiency, cartridges equipped with EPDM seals are suitable for systems using phosphate ester fluids but should avoid petroleum-based fluids to prevent seal damage. The valve employs a wet armature design which means that the working fluid surrounds the armature and can be affected by heat generated from prolonged coil energization. Notably, water-glycol mixtures may degrade at high temperatures over time. A notable feature of this product is its high-efficiency solenoid magnetic design that provides strong spool actuating force per watt expended. This ensures reliable shifting of the valve. The coils used in this model are interchangeable with other Sun Series 1 solenoid products and offer flexible installation options with coil connector ratings up to IP69K for enhanced environmental protection. The DNDATXN612N incorporates Sun's floating style construction aimed at reducing internal parts binding due to excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this cartridge valve stands out as a robust solution for demanding 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.
