The Sun Hydraulics DNDASYV2E24V (DNDASYV2E24V) is a solenoid-operated, 4-way, 2-position cartridge valve designed for directional control with a direct-acting, balanced spool configuration. It features a soft shift capability that minimizes system shock during valve actuation, making it suitable for applications where reduced hydraulic shock is desired. However, users should note that the soft shift feature may result in lower performance limits compared to standard cartridges and should not be relied upon for precise timing applications. For such requirements, Sun's electroproportional valves are recommended. This valve is interchangeable with standard cartridges and includes a push-type manual override control for easy operation. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. The valve supports a capacity of 4 gpm (15 L/min) and incorporates a wet armature design to enhance efficiency by allowing the working fluid to cool the coil. This design can lead to varnish formation over time in certain fluids like water-glycol mixtures when exposed to prolonged heat. For optimal soft shift performance, port 1 must maintain positive pressure. The valve also offers various coil connector options with ratings up to IP69K for enhanced environmental protection. Installation requires a torque range of 30\u201335 lbf ft (41\u201347 Nm), and the unit has a compact form factor with dimensions like a solenoid tube diameter of .75 in (19 mm) and hex size of .78 in (22.2 mm). The floating style construction minimizes internal binding risks due to installation or machining variations, ensuring reliable operation across diverse applications.

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.
