The Sun Hydraulics DNDAXLN712 (DNDAXLN712) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This versatile directional valve is engineered for high-performance applications, with a solenoid tube assembly fatigue rated for up to 5000 psi (350 bar), ensuring reliable operation under demanding conditions. Unlike pilot-operated valves, this direct-acting model requires no minimum hydraulic pressure to function, making it suitable for various hydraulic systems. The valve offers multiple manual override options; however, these are not compatible with weatherized coils. For models equipped with the D or L control, the manual override's detent mechanism is intended for temporary actuation and has an estimated mechanical life of around 7,000 cycles. The DNDAXLN712 utilizes a wet armature design where the working fluid surrounds the armature and absorbs heat generated by the coil. Users should be aware that certain fluids like water-glycol mixtures may degrade over time due to this heat exposure. A wide range of coil termination and voltage choices are available to meet specific application requirements, with options providing surge protection and IP69K-rated connectors for enhanced environmental resistance. This valve incorporates Sun's floating style construction to minimize internal component binding due to installation torque or cavity machining variations. It supports a maximum flow capacity of 10 gpm (40 L/min) and can handle operating pressures up to 5000 psi (350 bar). The typical response time is approximately 50 ms, with a switching frequency capability of up to 15,000 cycles per hour. The valve's compact design includes a solenoid tube diameter of .75 inches (19 mm) and weighs about .60 lbs (.30 kg), making it both efficient and easy to integrate into existing systems.

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.
