The Sun Hydraulics DNDASCV212N (DNDASCV212N) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with a soft shift feature designed to minimize system shock during valve actuation. This feature makes the valve ideal for applications where reducing hydraulic shock is crucial, although it may not be suitable for situations requiring precise timing control. The soft shift increases response time, typically ranging from 150 ms to 300 ms, depending on factors like flow and pressure. The valve incorporates a push-type manual override control but is not compatible with weatherized coils when using this function. It supports a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 4 gpm (15 L/min). The valve's solenoid tube assembly is fatigue-rated for high-pressure service and utilizes a wet armature design. This construction helps achieve high efficiency in solenoid operation, providing reliable spool actuation force per watt expended. Additionally, the valve's design minimizes the risk of internal parts binding due to excessive installation torque or machining variations. It fits into cavity T-31A and weighs approximately 0.60 lb (0.30 kg). For consistent performance, port 1 should maintain positive pressure, and various coil connector options offer environmental protection ratings up to IP69K.

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.
