The Sun Hydraulics DNDAXTN614 (DNDAXTN614) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve is fatigue-rated for service up to 5000 psi (350 bar) and operates efficiently without the need for minimum hydraulic pressure. It features a wet armature design, which allows the working fluid to surround the armature, enhancing heat dissipation from the coil. This characteristic is particularly relevant when using fluids like water-glycol mixtures that may degrade at high temperatures over time. The valve's unique magnetic design ensures high efficiency with significant spool actuating force per watt expended, leading to reliable operation. The DNDAXTN614 offers various manual override options, including configurations without manual override. For models with D or L controls, the detent mechanism in the manual override is intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The cartridge accommodates systems using phosphate ester fluids through its EPDM seals but should not be exposed to petroleum-based fluids as they can damage these seals. This valve supports a wide range of coil termination and voltage options, some with surge protection capabilities. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Additionally, coil connector options are available with ratings up to IP69K for enhanced environmental protection. Designed with Sun's floating style construction, this cartridge minimizes internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into cavity T-31A and belongs to Series 1, offering a capacity of up to 10 gpm (40 L/min). The typical response time is around 50 ms, and it can handle switching frequencies up to 15,000 cycles per hour.

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.
