The Sun Hydraulics DNDAXLV814N (DNDAXLV814N) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This versatile directional valve is engineered for reliable performance in hydraulic systems, with a solenoid tube assembly rated for fatigue at pressures up to 5000 psi (350 bar). It operates without the need for minimum hydraulic pressure and offers several manual override options, including models without a manual override. Notably, manual overrides with detent mechanisms are designed for temporary actuation and have an estimated mechanical life of around 7,000 cycles. The valve is compatible with EPDM seals for phosphate ester fluid systems but should not be exposed to petroleum-based fluids. This cartridge utilizes a wet armature design that enables the working fluid to cool the coil when energized, though care must be taken with fluids like water-glycol mixtures due to potential varnish formation over time. A range of coil termination and voltage options are available to suit various applications, with interchangeable coils across Sun Series 1 solenoid products. The high-efficiency magnetic design of the solenoid delivers robust actuating force per watt used, ensuring dependable valve shifting. For added environmental protection, weatherized coils and kits are offered with IP69K-rated coil connectors. The DNDAXLV814N model features Sun's floating style construction to reduce binding risks from installation torque or machining variations. It fits into T31A cavities and has a capacity of 10 gpm (40 L/min), with typical response times around 50 ms and maximum leakage rates at specified conditions of 10 in\u00b3/min (160 cc/min). The valve can handle switching frequencies up to 15,000 cycles per hour and requires specific installation torque settings between 30-35 lbf ft (41-47 Nm).

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.
