The Sun Hydraulics DNDASEN912 (DNDASEN912) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with a soft shift capability. This soft shift attribute significantly minimizes system shock during valve actuation, making it suitable for applications where reducing hydraulic shock is crucial. However, for applications requiring precise timing or ramping control, Sun's electro-proportional valves are recommended as the soft shift feature may not suffice. The valve's response time ranges from 150 ms to 300 ms and is influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, port 1 should maintain positive pressure. The DNDASEN912 model includes a push-type manual override control but is incompatible with weatherized coils and other manual control options like T or D unless installed later in the field. It boasts a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar) and employs a wet armature design that can impact fluid stability if the coil remains energized over extended periods. The high-efficiency solenoid design ensures reliable spool actuation with minimal energy expenditure. This cartridge utilizes Sun's floating style construction to prevent internal part binding due to excessive installation torque or machining variations. It fits into cavity T-31A and has a capacity of 4 gpm (15 L/min). The maximum operating pressure is capped at 5000 psi (350 bar), while leakage at 110 SUS (24 cSt) reaches up to 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar). The valve requires an installation torque of 30-35 lbf ft (41-47 Nm) and 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.
