The Sun Hydraulics DNDAXDV912 (DNDAXDV912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), providing robust performance without requiring a minimum hydraulic pressure for operation. It offers multiple manual override options, though these are not compatible with weatherized coils. For models featuring the D or L control, the manual override's detent mechanism is intended for temporary actuation and has a mechanical life expectancy of roughly 7,000 cycles. The DNDAXDV912 is suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, these seals should not be exposed to petroleum-based fluids. Its wet armature design allows the working fluid to cool the armature but may affect fluid integrity if energized for extended periods. The solenoid's efficient magnetic design ensures high spool actuating force per watt expended, facilitating reliable valve shifting. A variety of coil termination and voltage options are available, including those with surge protection. This cartridge employs Sun's floating style construction to minimize potential binding from excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into T31A cavities and belongs to Series 1, offering a capacity of 10 gpm (40 L/min). The valve supports a maximum operating pressure of 5000 psi (350 bar) with typical response times around 50 ms. Additional features include interchangeable coils with other Sun Series 1 solenoids and IP69K-rated connector options for enhanced environmental protection. The valve measures .75 inches in solenoid tube diameter and requires an installation torque between 30-35 lbf ft (41-47 Nm).

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.
