The Sun Hydraulics DNDASYV714 (DNDASYV714) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with a soft shift capability that minimizes system shock during valve actuation. This valve is ideal for applications where reduced hydraulic shock is beneficial, although it is not recommended for scenarios requiring precise timing control. The soft shift design results in longer response times compared to standard solenoids, with typical response times ranging from 150 ms to 300 ms depending on variables such as flow rate, pressure, and oil viscosity. For optimal performance, it is advised that port 1 maintains positive pressure. This cartridge includes a push-type manual override control but does not support other manual control options like T or D in conjunction with the soft shift feature; however, these can be installed post-purchase if needed. The solenoid tube assembly of the DNDASYV714 is rated for fatigue at pressures up to 5000 psi (350 bar), utilizing a wet armature design which exposes the working fluid to coil-generated heat\u2014a consideration when using certain fluids like water-glycol mixtures over extended periods. The valve's magnetic design ensures high efficiency by maximizing spool actuating force per Watt used. It incorporates Sun's floating style construction to prevent internal part binding due to installation torque or machining variations in the cavity/cartridge interface. The DNDASYV714 fits into a T-31A cavity and offers a capacity of 4 gpm (15 L/min). Additional features include coil connector options rated up to IP69K for enhanced environmental protection and compatibility with various weatherized coils and kits.

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.
