The Sun Hydraulics DNDASYN4E24V (DNDASYN4E24V) is a solenoid-operated 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design with a soft shift capability. This soft shift feature significantly reduces system shock during valve actuation, making it suitable for applications where minimizing hydraulic noise and vibrations is critical. However, it should be noted that the performance limits are lower compared to standard cartridges, and it may not be ideal for applications requiring precise timing control. For such applications, Sun's electro-proportional valves are recommended. The valve's response time varies depending on several factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. Typically, the response time ranges from 150 ms to 300 ms. For consistent performance of the soft shift feature, it is important that port 1 maintains a positive pressure. The valve includes a push-type manual override control; however, other manual control options cannot be ordered with the soft shift control but can be installed in the field if needed. This cartridge utilizes a wet armature design which allows working fluid to surround the armature and dissipate heat generated by the coil. This design enhances solenoid efficiency by providing high spool actuating force per watt expended which ensures reliable valve shifting even under demanding conditions. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar). Additionally, various coil connector options provide protection ratings up to IP69K for enhanced environmental resilience. Designed with Sun\u2019s floating style construction, this valve minimizes potential binding of internal parts due to excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 4 gpm (15 L/min) and maximum operating pressure of 5000 psi (350 bar), this versatile component serves as an effective solution in hydraulic systems requiring controlled actuation transitions while maintaining robust performance standards.

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.
