The Sun Hydraulics DMDASPN548 (DMDASPN548) is a solenoid-operated, 3-way, 2-position cartridge valve designed for hydraulic system applications requiring reliable directional control. This direct-acting, balanced spool valve features a unique soft shift option that mitigates shock from valve actuation, enhancing system longevity though it is not recommended for critical timing applications. Instead, Sun Hydraulics suggests considering their electro-proportional valves for precise control needs. The valve's soft shift design notably increases the response time ranging between 150 ms to 300 ms depending on variables such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. To maintain consistent performance, it is advised that port 1 remains at positive pressure. A push-type manual override is included with the valve for added control flexibility; however, it should be noted that this feature is incompatible with weatherized coils. Constructed to withstand pressures up to 5000 psi (350 bar), the solenoid tube assembly of the DMDASPN548 is fatigue rated for demanding applications. The wet armature design of the solenoid ensures that the working fluid surrounds the armature which may affect fluid integrity over prolonged energized periods. Special attention should be given to the type of fluid used as EPDM seals within the cartridge are specifically intended for phosphate ester fluids and can be damaged by petroleum-based substances. Additionally, this model incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 5 gpm (20 L/min) and featuring an array of coil connector options rated up to IP69K for environmental resilience, the DMDASPN548 offers robust performance and flexibility in a compact design suitable for various hydraulic applications.

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.
