The Sun Hydraulics DNDASNN724N (DNDASNN724N) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with an integrated soft shift feature. This feature is specifically engineered to minimize system shock during valve actuation, making it suitable for applications where gentle transitions are beneficial. However, the soft shift function should not be relied upon for applications requiring precise timing; for such needs, Sun\u2019s electro-proportional valves offer more accurate control. The response time of this valve ranges from 150 ms to 300 ms and varies based on flow, pressure, coil voltage, oil viscosity, and ambient temperature. It is recommended that port 1 maintain positive pressure to ensure consistent performance. The DNDASNN724N includes a push-type manual override control for added operational flexibility. While other manual controls can be installed in the field, they are not initially compatible with the soft shift model when ordered. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), utilizing a wet armature design that allows the working fluid to cool the armature but may lead to varnish formation with certain fluids over time. This high-efficiency solenoid valve offers robust performance with a magnetic design that provides significant spool actuating force per watt of power consumed. It supports various coil connector options with ratings up to IP69K for enhanced environmental protection. The construction features Sun\u2019s floating style design to reduce potential internal binding due to installation torque or machining variations. With a capacity of 4 gpm (15 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve is designed for reliable operation in demanding conditions while maintaining minimal leakage rates.

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.
