The Sun Hydraulics DNDATHV297 (DNDATHV297) is a solenoid-operated 4-way, 2-position cartridge valve designed for efficient and reliable directional control in hydraulic systems. This direct-acting, balanced spool valve operates without the need for minimum hydraulic pressure, offering versatility in application. The solenoid tube assembly is robustly fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Users have the option to select from various manual override configurations, though it is important to note that manual overrides are incompatible with weatherized coils. For models featuring D or L controls, the manual override's detent mechanism supports temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. This valve employs a wet armature design, allowing the working fluid to surround the armature and manage heat dissipation from the coil. However, users should be aware that prolonged coil energization can lead to fluid breakdown in certain mixtures like water-glycol, potentially affecting valve function. The DNDATHV297 offers a wide range of coil termination and voltage options, including some with surge protection. Its unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended. The cartridge features Sun's floating style construction to reduce internal binding risks due to excessive torque or machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). With a typical response time of 50 ms and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this valve is suitable for high-frequency applications up to 15,000 cycles per hour. The DNDATHV297 also offers interchangeable coils compatible with other Sun Series 1 products and provides IP69K-rated connector options for enhanced environmental protection.

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.
