The Sun Hydraulics DNDASUV212N (DNDASUV212N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for applications requiring direct-acting, balanced spool directional control with a soft shift feature. This valve is engineered to minimize system shock during actuation, making it suitable for systems where gentle transitions are crucial. While the soft shift feature reduces shock, it should not be relied upon in scenarios demanding precise timing; for such needs, consider electroproportional valves. The response time varies between 150 ms and 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift function, port 1 should maintain positive pressure. The DNDASUV212N includes a push-type manual override control but does not support T or D manual control options when using the soft shift feature; these can be retrofitted if necessary. Note that manual override is incompatible with weatherized coils. The valve's solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar), utilizing a wet armature design that enhances efficiency by providing high actuating force per watt expended. This design also implies that working fluid surrounds the armature and may affect function if exposed to high temperatures over extended periods. With a capacity of 4 gpm (15 L/min) and maximum operating pressure of 5000 psi (350 bar), the valve incorporates Sun\u2019s floating style construction to prevent internal binding due to installation torque or machining variations. It features coil connector options rated up to IP69K for robust environmental protection and is compatible with additional weatherized coils and kits. The cartridge's cavity size is T-31A in series 1, with a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar).

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.
