The Sun Hydraulics DMDASAV548 (DMDASAV548) is a solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its soft shift feature, which helps to mitigate shock during valve actuation by increasing the response time, typically ranging from 150 ms to 300 ms. While this feature enhances the operational smoothness, it is not suitable for applications requiring precise timing control, where electro-proportional valves would be better suited. The DMDASAV548 offers a manual override control with a push-type mechanism, although it should be noted that weatherized coil options are incompatible with this manual functionality. The valve operates effectively within a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). It supports various seal materials including EPDM for phosphate ester fluids, though exposure to petroleum-based fluids can damage these seals. This model incorporates Sun Hydraulics' floating style construction which minimizes internal part binding due to installation torque or machining variations of the cavity/cartridge. Additionally, the solenoid design of the DMDASAV548 is highly efficient, providing strong spool actuating force per watt expended which ensures reliable valve shifting. With coil connector options rated up to IP69K and additional weatherized coils available for enhanced environmental protection, this valve is versatile for different operating environments. Designed with a wet armature setup, it requires consideration of fluid type and operation duration as heat from prolonged coil energization may degrade certain hydraulic fluids.

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.
