The Sun Hydraulics DNDASDV71219 (DNDASDV71219) is a solenoid-operated, 4-way, 2-position cartridge valve designed for directional control with an integrated soft shift feature to minimize system shock during valve actuation. This balanced spool direct-acting valve is ideal for applications where reducing hydraulic shock is critical but precise timing is not essential. It offers a response time ranging from 150 ms to 300 ms, which can vary based on flow, pressure, coil voltage, oil viscosity, and ambient temperature. The soft shift cartridge can be interchanged with standard cartridges though it operates at lower performance limits. For consistent operation, port 1 should maintain positive pressure. The valve includes a push-type manual override control and supports coil connector options rated up to IP69K for enhanced environmental protection. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar) and employs a wet armature design that immerses the armature in the working fluid to dissipate heat generated by the coil. However, users should be cautious of fluid breakdown in water-glycol mixtures under prolonged energization. The high-efficiency solenoid design ensures reliable shifting with high spool actuating force per watt expended. Installation considerations include a cavity size T-31A with a series capacity of 4 gpm (15 L/min) and recommended installation torque between 30-35 lbf ft (41-47 Nm). The valve's construction minimizes internal part binding due to excessive torque or machining variations. With dimensions including a manual override stroke of .10 inches and a solenoid tube diameter of .75 inches, this versatile component weighs approximately .60 lb (.30 kg) and comes with an optional Viton seal kit for added durability in demanding conditions.

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.
