The Sun Hydraulics DNDASCV714 (DNDASCV714) is a solenoid-operated 4-way, 2-position cartridge valve designed with a direct-acting, balanced spool directional feature and a soft shift mechanism. This soft shift feature is engineered to significantly reduce system shock during valve actuation, although it may not be suitable for applications requiring precise timing control. For such applications, Sun's electro-proportional valves are recommended. The DNDASCV714 offers interchangeability with standard cartridges but operates under lower performance limits. Its response time varies between 150 ms and 300 ms depending on factors like flow, pressure, coil voltage, oil viscosity, and ambient temperature. To ensure consistent performance of the soft shift function, maintaining positive pressure at port 1 is advised. The valve incorporates a push-type manual override control for ease of use; however, other manual control options are not compatible with the soft shift control but can be installed in the field if necessary. Notably, manual override functionality is incompatible with weatherized coils. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar) service and features a wet armature design that allows working fluid exposure to coil-generated heat\u2014a consideration when using fluids like water-glycol mixtures over extended periods. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per Watt expended. Coil connector options offer protection ratings up to IP69K for enhanced environmental protection. The DNDASCV714 utilizes Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations in cavity-cartridge assemblies. It fits into a T-31A cavity and supports capacities up to 4 gpm (15 L/min), with maximum operating pressures reaching 5000 psi (350 bar).

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.
