The Sun Hydraulics DNDAXYV212 (DNDAXYV212) is a solenoid-operated, 4-way, 2-position cartridge valve designed for high-efficiency and reliable performance in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure and is fatigue-rated for service up to 5000 psi (350 bar). The unique magnetic design of the solenoid ensures high spool actuating force per watt, which contributes to dependable valve shifting. It features a wet armature design that allows the working fluid to surround the armature, helping manage heat generated by the coil. However, prolonged energization can lead to fluid breakdown in certain mixtures like water-glycol. The DNDAXYV212 offers several manual override options, though note that these are not compatible with weatherized coils. The manual override mechanism has a mechanical life expectancy of about 7,000 cycles when using D or L control models. Cartridges with EPDM seals are suitable for systems utilizing phosphate ester fluids but should avoid petroleum-based substances as these can damage the seals. This valve incorporates Sun\u2019s floating style construction to reduce internal component binding due to installation torque or machining variations. It fits into a T-31A cavity and supports a flow capacity of up to 10 gpm (40 L/min). The device's response time is approximately 50 ms with maximum leakage at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). With interchangeable coils compatible with other Sun Series 1 solenoid products and various termination options available\u2014including IP69K-rated connectors\u2014this model provides versatility and robust environmental protection. The DNDAXYV212 also supports switching frequencies up to 15,000 cycles per hour and requires specific installation torque parameters for optimal performance.

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.
