The Sun Hydraulics DNDASNV614 (DNDASNV614) is a solenoid-operated, 4-way, 2-position cartridge valve with a direct-acting, balanced spool and a soft shift feature. This feature is designed to minimize system shock during valve actuation but may not be suitable for applications requiring precise timing control. The valve's response time varies between 150 ms to 300 ms, depending on factors such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. It incorporates a push-type manual override control and offers reliable valve shifting due to its high-efficiency solenoid design. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar) service pressure. This cartridge valve utilizes a wet armature design, which allows the working fluid to surround the armature and absorb heat generated by the coil. However, this can lead to breakdown in certain fluids over time if the coil remains energized for extended periods. To ensure consistent performance of the soft shift feature, port 1 should maintain positive pressure. The cartridge is interchangeable with standard cartridges but has lower performance limits. The DNDASNV614 features Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. It has a capacity of 4 gpm (15 L/min), maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and requires an installation torque of 30 - 35 lbf ft (41 - 47 Nm). The manual override stroke measures .10 inches (2.5 mm), with an override force requirement of 5 lbs/1000 psi (33 N/100 bar) at port 1. The valve weighs approximately .60 lb (.30 kg) and fits into cavity T-31A from Series 1 offerings.

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.
