The Sun Hydraulics DMDASPN848 (DMDASPN848) is a solenoid-operated, 3-way, 2-position cartridge valve designed for hydraulic applications requiring directional control. This direct-acting, balanced spool valve is notable for its soft shift feature, which moderates hydraulic shock during valve actuation, enhancing system longevity and reducing noise. However, it is not suitable for applications where precise timing control is critical; for such requirements, electro-proportional valves are recommended. The valve's soft shift mechanism increases response times significantly compared to standard solenoids, with typical response times ranging between 150 ms to 300 ms depending on various factors including flow rate and oil viscosity. The valve operates optimally when port 1 maintains positive pressure. It features a push-type manual override control and incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as it can affect fluid integrity under prolonged energized conditions. Constructed with an innovative magnetic design, the DMDASPN848 achieves high efficiency and reliable valve shifting with minimal power expenditure. It also boasts a fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly. The valve supports various coil connector options with ratings up to IP69K for enhanced environmental protection against dust and moisture ingress. This model uses EPDM seals configured specifically for phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, the DMDASPN848 benefits from Sun\u2019s floating style construction which minimizes internal part misalignment due to installation variances or excessive torque. With a maximum flow capacity of 5 gpm (20 L/min) and capable of handling pressures up to 5000 psi (350 bar), this cartridge is essential for robust hydraulic systems requiring reliable directional control without the need for high-speed actuation.

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.
