The Sun Hydraulics DMDASAN848 (DMDASAN848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring reliable directional control. This direct-acting, balanced spool valve features a unique soft shift feature that minimizes hydraulic shock during actuation, enhancing system longevity and performance stability. Although the soft shift design increases response times (typically between 150 ms to 300 ms), it offers smoother transitions compared to standard solenoid valves. This model is equipped with a push-type manual override control, providing an additional layer of operational flexibility. The valve is designed with a wet armature setup where the working fluid surrounds the armature, which is crucial in scenarios where the coil may be energized for extended periods. Users should note that this design can affect fluid integrity over time, particularly with water-glycol mixtures. The DMDASAN848 operates effectively within a flow capacity of 5 gpm (20 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It features robust EPDM seals optimized for phosphate ester fluids, though these seals are susceptible to damage by petroleum-based substances. Further enhancing its utility and durability, the valve incorporates Sun\u2019s floating style construction which mitigates internal part binding due to installation torque or cavity/cartridge machining discrepancies. With options for various coil connector ratings up to IP69K and additional weatherized coils available, this model ensures reliable performance in diverse environmental conditions. The compact design with a weight of just .60 lb (0.30 kg) and minimal installation dimensions makes it suitable for various application setups requiring precise hydraulic control without spatial constraints.

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.
