The Sun Hydraulics DNDASNN214 (DNDASNN214) is a solenoid-operated, 4-way, 2-position cartridge valve designed for directional control in hydraulic systems. This direct-acting, balanced spool valve features a soft shift capability, which significantly reduces system shock during actuation. While it offers lower performance limits compared to standard cartridges, the soft shift feature enhances system reliability by minimizing abrupt pressure changes. However, it is not recommended for applications requiring precise timing control; for such needs, electro-proportional valves are advised. The typical response time of this valve ranges from 150 to 300 milliseconds, influenced by factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance with the soft shift feature, maintaining a positive pressure at port 1 is crucial. The DNDASNN214 includes a push-type manual override control but does not support other manual controls when utilizing the soft shift function. It has a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service and employs a wet armature design to enhance efficiency and reliability. This design helps dissipate heat generated by the coil but requires consideration of fluid compatibility due to potential thermal degradation over time. The valve's construction minimizes internal part binding risks due to installation torque or machining variations. It fits into a T-31A cavity and supports capacities up to 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with leakage rates capped at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The manual override requires a force of approximately 5 lbs/1000 psi (33 N/100 bar) on port 1 and features a stroke length of .10 inches (2.5 mm). With its robust design and versatile application capabilities, this valve is ideal for various hydraulic system configurations requiring reliable directional control with minimal shock impact.

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.
