The Sun Hydraulics DNDASCV4E24V (DNDASCV4E24V) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise fluid control with a soft shift feature to minimize system shock during actuation. This direct-acting, balanced spool directional valve is ideal for applications where reduced shock is critical, although it may not be suitable for scenarios requiring precise timing or ramping control. The soft shift design results in longer response times compared to standard solenoids, typically ranging from 150 ms to 300 ms depending on factors like flow and pressure. For optimal performance, port 1 should maintain positive pressure. The valve features a push-type manual override but does not support other manual options when the soft shift control is employed. It operates efficiently under a maximum pressure of 5000 psi (350 bar) and has a capacity of 4 gpm (15 L/min). The solenoid's wet armature design ensures high efficiency and reliability but requires consideration of fluid compatibility due to potential heat exposure. Coil connector options provide environmental protection ratings up to IP69K, with additional weatherized coils available. The valve's construction minimizes internal binding risks due to installation torque or machining variations. With a compact design featuring a .75-inch solenoid tube diameter and .60 lb weight, it offers ease of installation with a torque requirement of 30-35 lbf ft (41-47 Nm). The DNDASCV4E24V incorporates Sun's floating style construction for enhanced durability and includes Viton seal kits for maintenance needs.

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.
