The Sun Hydraulics DNDASCV524 (DNDASCV524) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with an integrated soft shift feature. This design minimizes system shock during valve actuation, making it suitable for applications where reducing hydraulic noise and vibration is crucial. While the soft shift mechanism offers smoother transitions, it may not be ideal for scenarios requiring precise timing; in such cases, Sun's electro-proportional valves are recommended. The valve's response time varies between 150 ms to 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, port 1 should maintain positive pressure. This model includes a push-type manual override control but does not accommodate other manual control options like T or D in its standard configuration; these can be installed later if needed. However, it's important to note that manual override functions are incompatible with weatherized coils. Designed for durability, the solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar). The valve employs a wet armature design that allows working fluid exposure to coil-generated heat\u2014fluids like water-glycol mixtures may degrade over time under these conditions. The solenoid's unique magnetic design ensures high efficiency by providing substantial spool actuating force per watt consumed. With coil connector options rated up to IP69K and additional weatherized kits available, this model offers robust environmental protection. The valve incorporates Sun\u2019s floating style construction to reduce internal component binding due to excessive installation torque or machining variations in the cavity/cartridge interface. It features a maximum capacity of 4 gpm (15 L/min), with leakage rates capped at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 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.
