The Sun Hydraulics DNDAXCN298 (DNDAXCN298) is a solenoid-operated 4-way, 2-position cartridge valve that is direct-acting with a balanced spool design. It is engineered for high performance, featuring a fatigue-rated solenoid tube assembly suitable for service pressures up to 5000 psi (350 bar). This valve requires no minimum hydraulic pressure for operation, making it versatile for various applications. It offers multiple manual override options, although models with the D or L control are designed for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The valve is compatible with systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The design incorporates a wet armature, allowing the working fluid to surround the armature and manage heat generated by coil operation. This feature is crucial if the coil remains energized over prolonged periods, especially in systems using water-glycol mixtures that may degrade into varnishes affecting functionality. The solenoid's magnetic design ensures high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. Additionally, coils are interchangeable within Sun Series 1 products and can be mounted in either direction. The DNDAXCN298 has a capacity of 10 gpm (40 L/min) and supports maximum operating pressures of up to 5000 psi (350 bar). Its response time is typically around 50 milliseconds, and it can handle switching frequencies up to 15,000 cycles per hour. The valve's construction minimizes internal part binding due to excessive torque or machining variations. Various coil termination and voltage options are available to suit different environmental conditions, including weatherized coils rated up to IP69K for enhanced protection.

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.
