The Sun Hydraulics DNDASTV223 (DNDASTV223) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with a soft shift capability. This design significantly reduces system shock during valve actuation, providing smoother operation compared to standard cartridges. However, it is important to note that while the soft shift feature enhances response time\u2014ranging from 150 ms to 300 ms based on various factors like flow and pressure\u2014it is not ideal for applications requiring precise timing. For such needs, electro-proportional valves are recommended. The DNDASTV223 includes a push-type manual override control but does not support certain other manual controls when the soft shift feature is present. The valve's solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar), utilizing a wet armature design that can impact fluid longevity if the coil remains energized for extended periods. Its magnetic design ensures efficient solenoid operation, yielding high actuating force per watt and reliable shifting. With coil connector options rated up to IP69K and additional weatherized coils available, the valve offers robust environmental protection. The floating style construction minimizes internal binding risks due to installation torque or machining variations. Key specifications include a capacity of 4 gpm (15 L/min), maximum operating pressure of 5000 psi (350 bar), and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min). Installation requires a torque range of 30-35 lbf ft (41-47 Nm). The valve's compact form factor features dimensions such as a solenoid tube diameter of .75 in (19 mm) and overall weight of .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.
