The Sun Hydraulics DNDASUV936 (DNDASUV936) 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 suitable for applications where reduced shock is desired, although it should not be relied upon for critical timing tasks. For precise control, Sun's electro-proportional valves are recommended. The soft shift feature increases response time compared to standard solenoids, with typical response times ranging from 150 ms to 300 ms depending on several factors such as flow rate and pressure. The valve operates optimally when port 1 maintains positive pressure and features a push-type manual override control. While other manual controls can be installed in the field, they cannot be ordered with the soft shift option. Note that manual override functionality is incompatible with weatherized coils. The solenoid tube assembly can withstand service pressures up to 5000 psi (350 bar) and employs a wet armature design that exposes the working fluid to coil-generated heat\u2014important for long-term coil energization considerations. This high-efficiency solenoid valve offers reliable shifting due to its unique magnetic design which maximizes spool actuating force per watt of power used. Users can choose from various coil connector options rated up to IP69K for enhanced environmental protection. Additionally, the valve incorporates Sun's floating style construction to prevent internal part binding from excessive installation torque or machining variations in cavity-cartridge interfaces. It fits into a T-31A cavity and has a capacity of 4 gpm (15 L/min), with maximum leakage at specified conditions being minimal. The model weighs approximately 0.60 lb (0.30 kg) and requires specific installation torque values between 30-35 lbf ft (41-47 Nm).

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.
