The Sun Hydraulics DMDASBV548 (DMDASBV548) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring directional control and soft shift functionality. This direct-acting, balanced spool valve is engineered to mitigate shock impacts during valve actuation, making it ideal for systems where sudden changes in direction could cause mechanical stresses. Notably, the soft shift feature significantly slows the valve's response time, typically ranging between 150 ms to 300 ms depending on various factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASBV548 includes a push-type manual override control which allows for manual operation of the valve in the event of an electrical power failure; however, this feature is not compatible with weatherized coils. Designed with robustness in mind, the solenoid tube assembly of the valve is fatigue rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Furthermore, this model uses EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based fluids as they can degrade the seals. Its wet armature design means that heat generated by the coil directly influences the working fluid which can be critical when dealing with certain fluid types over prolonged periods. For environmental protection and reliability in various operating conditions, different coil connector options are available with ratings up to IP69K. The construction incorporates Sun\u2019s floating style design which minimizes internal part binding due to installation torque or machining variations in cavity/cartridge setups. This model offers consistent performance with a maximum flow capacity of 5 gpm (20 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The DMDASBV548 is versatile enough for use in various hydraulic systems where smooth and controlled directional changes are crucial.

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.
