The Sun Hydraulics DNDASHV612 (DNDASHV612) is a solenoid-operated, 4-way, 2-position cartridge valve designed with a soft shift feature to minimize system shock during valve actuation. This direct-acting, balanced spool directional valve is interchangeable with standard cartridges but offers lower performance limits. It is particularly useful in applications where reducing shock is crucial, though it may not be suitable for situations requiring precise timing control; for those applications, electroproportional valves are recommended. The soft shift feature increases response time, which can vary from 150 ms to 300 ms depending on factors like flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance, port 1 should maintain positive pressure. The valve includes a push-type manual override control and supports various coil connector options rated up to IP69K for enhanced environmental protection. However, manual override functionality is not compatible with weatherized coils. The solenoid's high-efficiency magnetic design ensures reliable valve shifting by providing substantial spool actuating force with minimal power expenditure. The fatigue-rated solenoid tube assembly supports service pressures up to 5000 psi (350 bar), and the wet armature design helps manage heat dissipation when the coil is energized for extended periods. Installation considerations include a cavity size of T-31A and a series designation of 1 with a capacity of 4 gpm (15 L/min). The maximum operating pressure is set at 5000 psi (350 bar), while maximum valve leakage at specified conditions remains low at 10 in\u00b3/min (160 cc/min). The floating style construction minimizes internal part binding due to installation torque or machining variations. With dimensions such as a solenoid tube diameter of .75 in (19 mm) and an installation torque range of 30\u201335 lbf ft (41\u201347 Nm), this model 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.
