The Sun Hydraulics DNDAXHN914N (DNDAXHN914N) is a solenoid-operated 4-way, 2-position cartridge valve designed for reliable directional control in hydraulic systems. This direct-acting, balanced spool valve does not require a minimum hydraulic pressure to operate, making it versatile for various applications. It features a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar), ensuring durability and long-term performance. The valve's wet armature design allows the working fluid to surround the armature, which can impact function if the coil is energized for extended periods due to heat exposure. Notably, models with EPDM seals should be used exclusively with phosphate ester fluids to avoid damage from petroleum-based products. The DNDAXHN914N offers multiple manual override options, including configurations with temporary actuation detents. The manual control assembly is rated for approximately 7,000 cycles of mechanical life expectancy. This model also boasts a high-efficiency solenoid design that provides strong spool actuating force per watt expended, promoting reliable valve shifting. Various coil termination and voltage options are available, including those with surge protection and weatherized coils for enhanced environmental resistance. Installation is straightforward due to its floating style construction, minimizing internal part binding risks from excessive torque or machining variations. The valve fits into a T31A cavity and handles flow capacities up to 10 gpm (40 L/min). With a typical response time of 50 ms and switching frequency of up to 15,000 cycles per hour, this cartridge valve is engineered for high-performance applications where precision and reliability are paramount.

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.
