The Sun Hydraulics DNDAXSV297 (DNDAXSV297) is a solenoid-operated, 4-way, 2-position cartridge valve designed for reliable and efficient directional control in hydraulic systems. This direct-acting, balanced spool valve does not require a minimum hydraulic pressure for operation, making it versatile for various applications. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve features multiple manual override options, including models without manual override, though weatherized coils are incompatible with this functionality. The DNDAXSV297 incorporates a wet armature design where the working fluid surrounds the armature, which can affect the cartridge function if certain fluids like water-glycol mixtures are exposed to prolonged heat from the coil. This valve offers a wide variety of coil termination and voltage options with or without surge protection and interchangeable coils compatible with other Sun Series 1 solenoid products. With a cavity size of T-31A and a capacity of 10 gpm (40 L/min), this model ensures high efficiency with its unique magnetic design that provides high spool actuating force per watt expended. The maximum operating pressure is rated at 5000 psi (350 bar) with typical response times around 50 ms. It supports a maximum switching frequency of up to 15,000 cycles per hour and features minimal internal leakage at specified conditions. The DNDAXSV297 also includes Sun's floating style construction to reduce potential binding from installation torque or machining variations. It requires an installation torque between 30 to 35 lbf ft (41 to 47 Nm) and has a compact form factor weighing approximately .60 lb (0.30 kg). For systems using phosphate ester fluids, cartridges equipped with EPDM seals are recommended while avoiding exposure to petroleum-based substances that could damage these seals.

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.
