The Sun Hydraulics DNDASCV514 (DNDASCV514) 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 upon valve actuation, making it ideal for applications where minimizing hydraulic shock is crucial. However, the performance limits are lower compared to standard cartridges, and it's not recommended for applications requiring precise timing control. The response time varies from 150 ms to 300 ms depending on flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance with the soft shift feature, port 1 should maintain positive pressure. The valve includes a push-type manual override control but is not compatible with weatherized coils when using manual override functionality. It has a fatigue-rated solenoid tube assembly designed for up to 5000 psi (350 bar) service and utilizes a wet armature design that can affect fluid stability at high temperatures over prolonged periods. The unique magnetic design of the solenoid ensures high efficiency and reliable shifting. The DNDASCV514 incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or machining variations. It fits into T31A cavities and handles capacities up to 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with a maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The manual override requires a force of 5 lbs/1000 psi (33 N/100 bar) with a stroke length of .10 in. (2.5 mm). The valve's hex size is .78 in. (22.2 mm), with an installation torque of 30-35 lbf ft (41-47 Nm).

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.
