The Sun Hydraulics DNDASEV299 (DNDASEV299) is a solenoid-operated, 4-way, 2-position cartridge valve known for its direct-acting, balanced spool design with a soft shift feature. This soft shift capability significantly reduces system shock during valve actuation, making it ideal for applications where minimizing hydraulic shock is critical. However, for applications requiring precise timing or ramping control, Sun's electroproportional valves are recommended due to the limitations of the soft shift in such scenarios. The DNDASEV299 has a response time that varies between 150 ms to 300 ms depending on factors like flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal soft shift performance, it is advised that port 1 maintains a positive pressure. This valve includes a push-type manual override control but note that other manual override options cannot be ordered with the soft shift control though they can be installed in the field. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar) service and features a wet armature design which enhances efficiency but requires consideration of fluid compatibility due to potential heat exposure. The high-efficiency solenoid design ensures reliable valve shifting by providing substantial spool actuating force per watt expended. Additional features include various coil connector options with ratings up to IP69K for enhanced environmental protection and Sun's floating style construction which minimizes internal part binding from excessive installation torque or machining variations. With a capacity of 4 gpm (15 L/min), this model operates at maximum pressures of up to 5000 psi (350 bar) and has specific installation requirements such as a torque range of 30-35 lbf ft (41-47 Nm). The DNDASEV299 is compatible with Viton seal kits and weighs approximately .60 lb (.30 kg).

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.
