The Sun Hydraulics DNDASCN614 (DNDASCN614) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control with a soft shift feature. This soft shift capability significantly reduces system shock during valve actuation, although it may not be suitable for applications requiring precise timing control. In such cases, Sun's electro-proportional valves are recommended. The soft shift feature increases response time compared to standard solenoids, with typical response times ranging from 150 ms to 300 ms depending on flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift function, port 1 should maintain positive pressure. The valve includes a push-type manual override control and is designed for easy installation of other manual control options in the field. However, these manual overrides are incompatible with weatherized coils. This cartridge valve is fatigue-rated for service pressures up to 5000 psi (350 bar) and utilizes a wet armature design that immerses the working fluid around the armature. This design consideration is important as prolonged coil energization can cause certain fluids like water-glycol mixtures to degrade over time. The solenoid's magnetic design ensures high efficiency by providing significant spool actuating force per watt expended. Additionally, various coil connector options provide protection ratings up to IP69K for enhanced environmental resilience. The valve features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations within the cavity-cartridge interface. It fits into cavity T-31A and has a capacity of 4 gpm (15 L/min), making it suitable for various hydraulic applications requiring reliable directional control with minimized system shock.

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.
