The Sun Hydraulics DNDASUV612N (DNDASUV612N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control with a soft shift feature. This feature significantly reduces system shock during valve actuation, making it ideal for applications where minimizing hydraulic shock is crucial. However, it is important to note that the soft shift feature should not be relied upon for applications requiring precise timing; in such cases, Sun's electro-proportional valves are recommended. The valve's response time ranges from 150 ms to 300 ms and varies depending on flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, port 1 should maintain a positive pressure. This model includes a push-type manual override control but does not support other manual control options like T or D with the soft shift control. The solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), utilizing a wet armature design that ensures high efficiency and reliable shifting by generating high spool actuating force per watt expended. The valve's construction incorporates Sun's floating style design to reduce the risk of internal parts binding due to excessive installation torque or cavity-cartridge machining variations. The DNDASUV612N fits into cavity T-31A and belongs to Series 1 with a capacity of 4 gpm (15 L/min). It features coil connector options rated up to IP69K for enhanced environmental protection. The valve has a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). Additionally, it comes with a Viton seal kit (990431006) for effective sealing performance.

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.
