The Sun Hydraulics DNDASNV724N (DNDASNV724N) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with a soft shift capability. This soft shift feature significantly minimizes system shock during valve actuation, making it ideal for applications where smooth operation is critical. However, it should not be relied upon for precise timing control; for such needs, Sun's electro-proportional valves are recommended. The soft shift increases response time, which varies based on flow, pressure, coil voltage, oil viscosity, and ambient temperature\u2014typically ranging from 150 ms to 300 ms. For optimal performance, port 1 should maintain positive pressure. The valve includes a push-type manual override control but note that this function is incompatible with weatherized coils and other manual options like T or D must be installed in the field if needed. The solenoid tube assembly of the DNDASNV724N is fatigue-rated for service pressures up to 5000 psi (350 bar) and employs a wet armature design that exposes the working fluid to heat generated by the coil. This can affect certain fluids over time if the coil remains energized for prolonged periods. The high-efficiency solenoid design ensures reliable valve shifting by providing high spool actuating force per watt expended. Various coil connector options are available with ratings up to IP69K for enhanced environmental protection. This model features Sun's floating style construction to reduce internal part binding due to installation torque or machining variations. It fits in cavity T-31A and belongs to Series 1 with a capacity of 4 gpm (15 L/min). Maximum leakage is rated at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar), and it requires a manual override force of 5 lbs/1000 psi at Port 1 with an override stroke of .10 inches (2.5 mm). The solenoid tube diameter measures .75 inches (19 mm), and installation torque ranges between 30-35 lbf ft (41-47 Nm). The valve weighs approximately .60 lb (.30 kg) and uses Viton seal kit number 990431006.

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.
