The Sun Hydraulics DNDASUV914N (Material Number: DNDASUV914N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with an integrated soft shift mechanism. This valve is engineered to minimize system shock during actuation, making it suitable for applications where reducing hydraulic impact is crucial. Although the soft shift feature enhances response time, it is not intended for precision timing applications; for such needs, electro-proportional valves are recommended. The DNDASUV914N offers a typical response time ranging from 150 ms to 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It requires positive pressure at port 1 for consistent performance. This model includes a push-type manual override control and features a solenoid tube assembly rated for fatigue service up to 5000 psi (350 bar). The valve's wet armature design allows working fluid exposure to coil-generated heat; users should be cautious with fluids like water-glycol mixtures that degrade under prolonged heat exposure. The high-efficiency solenoid design ensures reliable valve shifting by maximizing spool actuating force per watt expended. The DNDASUV914N incorporates Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or cavity-cartridge machining variations. It fits into a T-31A cavity and belongs to Series 1 with a capacity of 4 gpm (15 L/min). The valve has maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar) and requires a manual override force of 5 lbs/1000 psi (33 N/100 bar) at port 1. It comes with various coil connector options rated up to IP69K for enhanced environmental protection.

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.
