The Sun Hydraulics DNDASRN614 (DNDASRN614) 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, although it results in slightly lower performance limits compared to standard cartridges. The soft shift function is beneficial in applications where shock reduction is prioritized but may not be suitable for tasks requiring precise timing or ramping control; in such cases, Sun's electro-proportional valves are recommended. The response time of the soft shift feature varies between 150 ms and 300 ms depending on factors such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance, it is advised to maintain a positive pressure at port 1. The valve includes a push-type manual override control; however, this functionality is incompatible with weatherized coils and other manual control options like T or D must be installed separately if required. The solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar) and uses a wet armature design that exposes the working fluid to coil heat\u2014important to consider if the coil remains energized for extended periods. The unique magnetic design of the solenoid ensures high efficiency by providing substantial spool actuating force per watt expended. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. With a cavity size of T-31A and a series capacity of 4 gpm (15 L/min), this valve offers reliable performance under demanding conditions.

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.
