The Sun Hydraulics DNDASRV514 (DNDASRV514) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control with a soft shift feature. This feature minimizes system shock during valve actuation, although it is not suitable for applications requiring precise timing control. The soft shift option results in increased response time compared to standard solenoids, with typical response times ranging from 150 ms to 300 ms, influenced by factors like flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance consistency, port 1 should be maintained at positive pressure. The valve includes a push-type manual override control but is incompatible with weatherized coils. Constructed with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, the valve features a wet armature design that can impact fluid stability under prolonged coil energization. The solenoid\u2019s magnetic design ensures high efficiency and reliable shifting by maximizing the actuating force per watt expended. It incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. Other specifications include a T31A cavity type, Series 1 classification, and a capacity of 4 gpm (15 L/min). Maximum operating pressure reaches 5000 psi (350 bar), while maximum leakage at 110 SUS (24 cSt) is limited to 10 in/min at 3000 psi (160 cc/min at 210 bar). The manual override requires a force of approximately 5 lbs/1000 psi at port one with a stroke of .10 inches (2.5 mm). The solenoid tube has a diameter of .75 inches (19 mm), and the valve hex size measures .78 inches (22.2 mm), with an installation torque range of 30-35 lbf ft (41-47 Nm). The model weighs .60 lbs (.30 kg) and uses Viton seal kits for effective sealing solutions.

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.
