The Sun Hydraulics DNDAXNV924N (DNDAXNV924N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This robust valve is engineered to perform under high-pressure conditions, with the solenoid tube assembly rated for fatigue at 5000 psi (350 bar). It operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The cartridge offers multiple manual override options, although these are incompatible with weatherized coils. Models with the D or L control feature a detent mechanism in the manual override intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. The valve employs EPDM seals suitable for systems using phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature and absorb heat from the coil, which can affect performance if energized for extended periods\u2014particularly in water-glycol mixtures that may degrade over time. The solenoid's magnetic design ensures high efficiency by delivering significant spool actuating force per watt expended. A wide array of coil termination and voltage options are available, including models with surge protection. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. Coil connectors provide ratings up to IP69K for enhanced environmental protection. The valve features Sun's floating style construction to mitigate internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. Key specifications include a T31A cavity type, Series 1 classification, a capacity of 10 gpm (40 L/min), typical response time of 50 ms, and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min).

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.
