The Sun Hydraulics DNDASDV624N (DNDASDV624N) is a solenoid-operated, 4-way, 2-position cartridge valve designed with a soft shift feature to minimize system shock during valve actuation. This direct-acting, balanced spool directional valve is ideal for applications where reducing shock is crucial, although it is not suitable for scenarios requiring precise timing control. The soft shift capability increases response time compared to standard solenoids, with typical times ranging from 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal soft shift performance, port 1 should maintain positive pressure. This model includes a push-type manual override control and offers high efficiency due to its unique magnetic design that provides substantial spool actuating force per watt of power used. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), employing a wet armature design that can impact the durability of certain fluids if the coil remains energized for extended periods. It features a cavity size of T-31A and belongs to Series 1 with a capacity of 4 gpm (15 L/min). The valve's maximum operating pressure stands at 5000 psi (350 bar), with maximum leakage rates of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The Sun Hydraulics DNDASDV624N requires an installation torque between 30 and 35 lbf-ft (41 to 47 Nm) and has a manual override stroke of .10 inches (2.5 mm). It incorporates floating style construction to reduce the risk of internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. Additional coil connector options are available with ratings up to IP69K for enhanced environmental protection.

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.
