The Sun Hydraulics DNDASHN2E12V (DNDASHN2E12V) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with a soft shift mechanism. This design significantly reduces system shock during valve actuation, providing smoother transitions compared to standard cartridges, although at lower performance limits. The soft shift feature is beneficial in applications where reducing shock is crucial; however, it should not be relied upon for precise timing control\u2014Sun\u2019s electro-proportional valves are recommended for such needs. Response times vary between 150 ms to 300 ms depending on flow, pressure, coil voltage, oil viscosity, and ambient temperature. Consistent soft shift performance requires port 1 to maintain positive pressure. The valve includes a push-type manual override control and supports easy installation of other manual control options in the field. Note that manual override functionality is incompatible with weatherized coils. This cartridge incorporates a fatigue-rated solenoid tube assembly designed for up to 5000 psi (350 bar) service and utilizes a wet armature design that can affect fluid stability over time due to heat exposure from the coil. Its unique magnetic design ensures high efficiency by maximizing spool actuating force per Watt expended. Coil connector options provide ratings up to IP69K for enhanced environmental protection. The valve employs Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. Key specifications include a capacity of 4 gpm (15 L/min), maximum operating pressure of 5000 psi (350 bar), and maximum valve leakage at 110 SUS (24 cSt) of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The model's weight is approximately .60 lb (.30 kg), with Viton seal kits available for maintenance needs.

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.
