The Sun Hydraulics DNDATNN297 (DNDATNN297) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. It features a solenoid tube assembly rated for 5000 psi (350 bar) service, making it suitable for high-pressure applications. This valve operates without the need for minimum hydraulic pressure, allowing versatile use in various systems. The DNDATNN297 offers multiple manual override options; however, note that manual override is not compatible with weatherized coils. The detent mechanism in models with D or L control is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. This valve employs a wet armature design, which means the working fluid surrounds the armature and absorbs heat generated by the coil. This design consideration is particularly important when using fluids like water-glycol mixtures that may degrade at high temperatures over time. The solenoid's magnetic design ensures high efficiency by providing significant spool actuating force per watt consumed, ensuring reliable shifting of the valve. The DNDATNN297 cartridge allows interchangeability of coils with other Sun Series 1 solenoid products and supports mounting in either direction. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. It incorporates Sun's floating style construction to minimize potential binding of internal parts due to excessive installation torque or cavity machining variations. Key specifications include a capacity of 10 gpm (40 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min). The valve has a switching frequency capability of up to 15,000 cycles/hr and requires manual override force of approximately 5 lbs/1000 psi at Port 1.

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.
