The Sun Hydraulics DNDASCN224N (DNDASCN224N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design with a soft shift feature. This soft shift capability significantly reduces system shock during valve actuation. Although it can be interchanged with the standard cartridge, it operates within lower performance limits and should not be relied upon for applications requiring precise timing control. For such needs, Sun's electro-proportional valves are recommended. The response time of this valve typically ranges from 150 ms to 300 ms and is influenced by flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal soft shift performance, port 1 should maintain positive pressure. The valve includes a push-type manual override control but does not support other manual control options like T or D when using the soft shift feature; these can be installed in the field if necessary. Note that manual override functionality is incompatible with weatherized coils. The solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar) and utilizes a wet armature design for enhanced solenoid efficiency and reliable valve shifting. Coil connector options are available with ratings up to IP69K for environmental protection. This model incorporates Sun's floating style construction to minimize potential internal binding due to installation or machining variations. It fits within cavity T-31A and has a capacity of 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with maximum leakage at specified conditions being 10 in\u00b3/min (160 cc/min). The valve features a hex size of .78 inches (22.2 mm) and requires an installation torque between 30 to 35 lbf ft (41 to 47 Nm). The model weighs .60 lb (.30 kg) and is compatible with Viton seal kits under part number 990431006.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve with a soft shift feature. The soft shift feature greatly reduces system shock due to valve actuation.

  • The soft shift cartridge is interchangeable with the standard cartridge, however, the performance limits are lower.
  • The soft shift feature can greatly reduce shock due to valve actuation but should not be counted upon in applications where timing is critical. If you need accurate ramping or timing control, consider Sun's electro-proportional valves.
  • The soft shift feature results in significant increase in response time over Sun's standard solenoid. Response time is dependant on flow, pressure, coil voltage, oil viscosity and ambient temperature. Typical response time ranges from 150 ms to 300 ms.
  • For consistent soft shift performance, port 1 should be at a positive pressure.
  • This valve includes a push-type manual override control. Other manual control options such as T or D, cannot be ordered with the soft shift control but can be installed easily in the field. See Twist/Lock Manual Override link above for details. Please note: Manual override functionality is not compatible with weatherized coils.
  • The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
  • 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.
  • 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.
  • 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.
