The Sun Hydraulics DNDAXRV712N (DNDAXRV712N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a solenoid tube assembly fatigue rated for service up to 5000 psi (350 bar), ensuring high performance and reliability in demanding applications. It operates without the need for minimum hydraulic pressure, making it versatile in various systems. A key feature is its wet armature design which allows the working fluid to surround the armature, mitigating heat effects from the coil. However, users should note that certain fluids like water-glycol mixtures may degrade under prolonged exposure to heat. The valve offers multiple manual override options, though it's important to remember that manual overrides are incompatible with weatherized coils. Models with D or L control have a detent mechanism for temporary actuation and boast a mechanical life expectancy of approximately 7,000 cycles. The cartridge accommodates EPDM seals suitable for phosphate ester fluids but unsuitable for petroleum-based fluids due to potential seal damage. With a cavity size of T-31A and Series 1 classification, this valve has a capacity of 10 gpm (40 L/min). It exhibits typical response times of around 50 ms and maximum leakage at specific conditions capped at 10 in\u00b3/min (160 cc/min). The solenoid's efficient magnetic design ensures reliable shifting with high spool actuating force per watt expended. Coil options are versatile, featuring interchangeable designs compatible with other Sun Series 1 products and offering IP69K-rated connector options for enhanced environmental protection. Installation requires specific torque settings between 30-35 lbf ft (41-47 Nm), and its compact build weighs just .60 lb (.30 kg). Seal kits are available in Viton material for both cartridge and coil assemblies.

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.
