The Sun Hydraulics DNDAXEN224 (DNDAXEN224) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 10 gpm (40 L/min). It incorporates a fatigue-rated solenoid tube assembly, ensuring durability under high-pressure conditions. The valve is direct actuated and does not require any minimum hydraulic pressure for operation, which makes it versatile for various applications. Notably, the DNDAXEN224 offers multiple manual override options, though it should be noted that manual override functions are not compatible with weatherized coils. For models equipped with the D or L control, the detent mechanism in the manual override is intended for temporary actuation with an estimated mechanical life expectancy of approximately 7,000 cycles. The valve utilizes EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to surround and cool the armature but can be affected by prolonged coil energization leading to varnish formation in certain fluids like water-glycol mixtures. A variety of coil termination and voltage options are available to suit different requirements, including those with surge protection features. Coils are interchangeable within Sun Series 1 solenoid products and can be installed in either direction on the tube. With its unique magnetic design yielding high efficiency and reliable valve shifting, this model also features IP69K-rated coil connector options for enhanced environmental protection. The floating style construction minimizes internal binding risks due to installation torque or machining variations, ensuring consistent performance across applications.

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.
