The Sun Hydraulics DNDASCV948 (DNDASCV948) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with a soft shift capability. This soft shift feature significantly reduces system shock during valve actuation, making it suitable for applications where minimizing hydraulic shock is crucial. However, it should be noted that this feature is not ideal for applications requiring precise timing control; for such needs, Sun's electro-proportional valves are recommended. The soft shift design leads to an increased response time compared to standard solenoids, with typical response times ranging from 150 ms to 300 ms depending on various factors such as flow rate and oil viscosity. For optimal performance, port 1 should maintain positive pressure. This valve includes a push-type manual override control, although other manual controls can be added in the field if necessary. The solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar), and the valve utilizes a wet armature design which may impact fluid choice due to potential heat-related breakdowns over time. The high-efficiency solenoid ensures reliable operation by maximizing spool actuating force per watt. Various coil connector options provide ratings up to IP69K for enhanced environmental protection. The DNDASCV948 features Sun's floating style construction that minimizes internal part binding due to installation torque or machining variations. It fits into a T-31A cavity and offers a flow capacity of up to 4 gpm (15 L/min). The maximum operating pressure is 5000 psi (350 bar), while leakage at specified conditions does not exceed 10 in\u00b3/min (160 cc/min). Valve installation requires torque between 30 - 35 lbf\u00b7ft (41 - 47 Nm), and the model weighs approximately .60 lb (.30 kg).

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.
