The Sun Hydraulics DNDASCN714 (DNDASCN714) is a solenoid-operated, 4-way, 2-position cartridge valve designed for directional control with a soft shift feature to minimize system shock during valve actuation. This direct-acting, balanced spool valve offers interchangeable compatibility with standard cartridges but operates under different performance limits. The soft shift feature significantly increases response time compared to Sun's standard solenoids, with typical response times ranging from 150 ms to 300 ms depending on variables such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. It is important to maintain positive pressure at port 1 for consistent performance. The valve includes a push-type manual override control for ease of use; however, other manual controls like T or D cannot be ordered with the soft shift but can be installed in the field. Note that manual override is not compatible with weatherized coils. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), utilizing a wet armature design where working fluid surrounds the armature. This design can affect functionality if the coil remains energized over long periods due to heat exposure. The solenoid's magnetic design ensures high efficiency and reliable shifting by providing high spool actuating force per watt expended. Coil connector options are available with ratings up to IP69K for environmental protection. This cartridge features Sun's floating style construction to reduce internal part binding due to installation torque or machining variations in the cavity/cartridge. With a capacity of 4 gpm (15 L/min) and maximum operating pressure of 5000 psi (350 bar), it provides dependable performance in hydraulic systems requiring smooth directional control transitions without abrupt shocks or disturbances.

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.
