The Sun Hydraulics DNDAXNV712 (DNDAXNV712) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient and reliable performance in hydraulic systems. This direct-acting, balanced spool directional valve is fatigue-rated for service up to 5000 psi (350 bar), requiring no minimum hydraulic pressure for operation. It offers various manual override options, though these are not compatible with weatherized coils. The DNDAXNV712 features a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil, a consideration when using fluids like water-glycol mixtures that may degrade under prolonged high temperatures. The solenoid's advanced magnetic design enhances efficiency by providing high spool actuating force per watt expended. This valve is part of Sun's Series 1 and fits into cavity T-31A with a capacity of 10 gpm (40 L/min). It boasts a fast typical response time of 50 ms and can handle a maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports a switching frequency of up to 15,000 cycles per hour. The manual override requires minimal force\u20145 lbs at 1000 psi\u2014and has a stroke length of .10 inches (2.5 mm). The DNDAXNV712 incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction, offering various termination and voltage options with surge protection capabilities. Coil connector options are rated up to IP69K for enhanced environmental protection. The valve has an installation torque requirement of 30-35 lbf ft (41-47 Nm) and weighs approximately .60 lb (.30 kg). Seal kits are available in Viton material for both cartridge and coil components.

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.
