The Sun Hydraulics DNDAXLV912 (DNDAXLV912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool directional valve requires no minimum hydraulic pressure to operate, making it versatile for various applications. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. It features a wet armature design, allowing the working fluid to surround the armature and be exposed to coil-generated heat. This design enhances efficiency but requires consideration of fluid type due to potential thermal degradation over time. The DNDAXLV912 offers multiple manual override options, including configurations with temporary actuation detents and models without manual overrides. It's important to note that manual overrides are incompatible with weatherized coils. The valve's solenoid boasts a unique magnetic design that provides high efficiency and reliable shifting by maximizing spool actuating force per watt expended. This valve is compatible with various coil termination and voltage options, some offering surge protection, and can accommodate interchangeable coils from other Sun Series 1 solenoid products. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The cartridge incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this valve supports rapid operation with minimal leakage at specified conditions. It also has a switching frequency capability of up to 15,000 cycles per hour. The DNDAXLV912 is suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids should be avoided as it may damage the 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.
