The Sun Hydraulics DMDASAN948 (DMDASAN948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems requiring reliable directional control. This direct-acting, balanced spool valve features a soft shift option which moderates the shock typically associated with valve actuation, making it suitable for applications sensitive to sudden changes in pressure or flow. However, it is not recommended for use in scenarios where precise timing control is critical; for such requirements, Sun Hydraulics suggests considering their electro-proportional valves instead. The soft shift model of the DMDASAN948 significantly increases response times compared to standard solenoid valves offered by Sun Hydraulics, with typical response times ranging from 150 ms to 300 ms depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It includes a push-type manual override and boasts a fatigue rating of 5000 psi (350 bar) for its solenoid tube assembly. Notably, this model uses EPDM seals suitable only for phosphate ester fluids and should not be exposed to petroleum-based fluids. This valve also features a wet armature design where the working fluid surrounds the armature. Prolonged energization of the coil can lead to high temperatures that may degrade certain fluid types like water-glycol mixtures. Additionally, its unique magnetic design enhances the efficiency of the solenoid, ensuring robust valve shifting with optimal energy usage. The DMDASAN948 supports various coil connector options with protection ratings up to IP69K and can be configured with additional weatherized coils for enhanced environmental protection. With a capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve integrates Sun's floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. This makes the DMDASAN948 an excellent choice for diverse hydraulic applications requiring both reliability and flexibility in component integration.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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 dependent 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
