The Sun Hydraulics DNDASHV2E24V (DNDASHV2E24V) 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 is ideal for applications where reducing system shock is crucial, although it should not be relied upon for critical timing control. For precise ramping or timing, consider Sun's electroproportional valves instead. The soft shift feature results in increased response times ranging from 150 ms to 300 ms depending on factors such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. It is recommended that port 1 maintains a positive pressure for consistent performance. The valve includes a push-type manual override control and features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. It employs a wet armature design where the working fluid surrounds the armature and absorbs heat generated by the coil; this can affect certain fluids like water-glycol mixtures over time. The solenoid's magnetic design ensures high efficiency with reliable shifting capabilities and offers coil connector options with ratings up to IP69K for enhanced environmental protection. This model utilizes Sun's floating style construction to reduce the risk of internal binding due to excessive installation torque or machining variations. It fits into cavity T-31A and has a capacity of 4 gpm (15 L/min). Installation requires torque between 30 - 35 lbf ft (41 - 47 Nm), and it weighs approximately .60 lb (0.30 kg). The valve comes with Viton seals under part number 990431006 for enhanced durability and compatibility with hydraulic systems.

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.
