The Sun Hydraulics DNDASCN512 (DNDASCN512) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with a soft shift capability. This particular feature significantly minimizes system shock during valve actuation, making it ideal for applications where gentle transitions are necessary. However, it is important to note that this soft shift feature may not be suitable for applications requiring precise timing control; in such cases, Sun\u2019s electro-proportional valves would be more appropriate. The valve\u2019s response time is influenced by various factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature, typically ranging from 150 ms to 300 ms. It incorporates a push-type manual override control for added versatility in operation. The DNDASCN512 operates within a maximum capacity of 4 gpm (15 L/min) and can withstand pressures up to 5000 psi (350 bar). For optimal performance consistency with the soft shift feature, port 1 should maintain positive pressure. Additionally, the valve's solenoid tube assembly is fatigue-rated for high-pressure service and designed with a wet armature to enhance efficiency and reliability. The unique magnetic design of the solenoid ensures high spool actuating force per watt used. Installation considerations include a cavity size of T-31A and an installation torque specification between 30 - 35 lbf ft (41 - 47 Nm). The valve's construction employs Sun's floating style technique to reduce potential binding issues due to installation torque or machining variations. For environmental protection needs, various coil connector options are available with ratings up to IP69K. The DNDASCN512 model weighs approximately .60 lb (0.30 kg), and its Viton seal kit can be ordered under part 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.
