The Sun Hydraulics DNDASRN212N (DNDASRN212N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with a soft shift capability. This valve is designed to minimize system shock during actuation, making it ideal for applications where smooth operation is critical. While the soft shift feature offers reduced system shock, it should not be relied upon in scenarios requiring precise timing; for such needs, electro-proportional valves are recommended. The response time of this valve varies between 150 ms and 300 ms depending on factors such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. The DNDASRN212N includes a push-type manual override control and supports field installation of other manual controls like T or D types. However, these are incompatible with weatherized coils. The solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), and the valve employs a wet armature design to enhance efficiency by surrounding the armature with working fluid. This configuration also influences thermal management when the coil remains energized for extended periods. For optimal performance with the soft shift feature, port 1 must maintain positive pressure. The solenoid's magnetic design provides high efficiency and reliable shifting by maximizing spool actuating force per watt consumed. The product offers various coil connector options with ratings up to IP69K for enhanced environmental protection. Additionally, Sun Hydraulics' floating style construction minimizes internal part binding risks due to installation torque or machining variations. The DNDASRN212N fits into cavity T-31A and belongs to Series 1 with a capacity of 4 gpm (15 L/min). It can handle maximum operating pressures of up to 5000 psi (350 bar), while leakage at specified conditions remains under 10 in\u00b3/min (160 cc/min). With a lightweight design weighing .60 lb (.30 kg), this valve also features Viton seal kits available for maintenance needs.

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.
