The Sun Hydraulics DNDAXNV71219 (DNDAXNV71219) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring robust performance in demanding hydraulic systems. It operates without the need for minimum hydraulic pressure and offers various manual override options, although these are not compatible with weatherized coils. The manual override's detent mechanism is intended for temporary actuation, with an estimated mechanical life expectancy of around 7,000 cycles. The cartridge is equipped with EPDM seals suitable for phosphate ester fluid systems but can be damaged by petroleum-based fluids. The wet armature design allows the working fluid to surround the armature, which may impact performance if the coil is energized for extended periods due to heat exposure. A wide range of coil termination and voltage options are available, featuring high efficiency and reliable valve shifting due to a unique magnetic design. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction, with connector options rated up to IP69K available. This model incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations. It fits into a T31A cavity and belongs to Series 1, boasting a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar). Typical response time is approximately 50 ms, with minimal leakage rates under specified conditions. The DNDAXNV71219 supports high switching frequency up to 15,000 cycles per hour and requires specific manual override force and stroke parameters during operation.

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.
