The Sun Hydraulics DNDAXSN814N (DNDAXSN814N) is a solenoid-operated 4-way, 2-position cartridge valve known for its direct-acting, balanced spool directional capabilities. This valve is designed for high-performance applications with a fatigue-rated solenoid tube assembly that can handle up to 5000 psi (350 bar) service pressure. It operates without requiring minimum hydraulic pressure, making it highly versatile. The cartridge offers several manual override options, though it's important to note that manual overrides are not compatible with weatherized coils. For models featuring the D or L control, the detent mechanism in the manual override is intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. This valve uses EPDM seals suitable for systems with phosphate ester fluids; however, they should not be exposed to petroleum-based fluids as these will damage the seals. The wet armature design allows working fluid to surround the armature and tolerate heat generated by the coil\u2014a crucial consideration when using fluids like water-glycol mixtures that may degrade over time under prolonged heat exposure. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Various coil termination and voltage options are available, including those with surge protection and ratings up to IP69K for enhanced environmental protection. With a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve has a typical response time of 50 ms and minimal leakage rates at specified conditions. Installation torque ranges between 30-35 lbf ft (41-47 Nm), emphasizing ease of integration into hydraulic systems.

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.
