The Sun Hydraulics DNDASEV624N (DNDASEV624N) is a solenoid-operated 4-way, 2-position cartridge valve designed for directional control applications with a focus on reducing system shock. This direct-acting, balanced spool valve features a soft shift capability that minimizes the impact of valve actuation, making it suitable for systems where gentle transitions are desired. However, the soft shift function results in lower performance limits and increased response times compared to standard cartridges, ranging from 150 ms to 300 ms depending on flow and pressure conditions. The valve is equipped with a push-type manual override control, although additional manual options can be installed if needed. It operates within a maximum pressure of 5000 psi (350 bar) and has a capacity of 4 gpm (15 L/min). The solenoid tube assembly is fatigue rated for high-pressure service, utilizing a wet armature design that ensures efficient heat dissipation but requires attention to fluid compatibility due to potential varnish formation at elevated temperatures. The solenoid's magnetic design enhances efficiency by delivering high actuating force per watt consumed. For environmental protection, coil connector options offer ratings up to IP69K, with additional weatherized coils available. The valve incorporates Sun's floating style construction to prevent internal binding from installation torque or machining variations. It fits into cavity T-31A and weighs approximately 0.60 lb (0.30 kg), with installation torque specifications between 30 to 35 lbf ft (41 to 47 Nm). This product is ideal for applications requiring reliable directional control with minimized hydraulic shock but should be used with caution in timing-critical systems where electroproportional valves may be more appropriate.

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.
