The Sun Hydraulics DMDASAN298 (DMDASAN298) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-efficiency hydraulic systems. This direct-acting, balanced spool directional valve is distinguished by its soft shift feature, which moderates the shock typically associated with valve actuation. Although this feature increases the response time\u2014ranging from 150 ms to 300 ms depending on various factors such as flow and pressure\u2014it is not suitable for applications requiring precise timing control, where electro-proportional valves might be preferable. The DMDASAN298 operates optimally when port 1 maintains positive pressure and includes a push-type manual override control. The valve's construction incorporates a wet armature design, meaning the armature is surrounded by working fluid which can affect performance if the coil remains energized over long periods. It is important to note that cartridges with EPDM seals are specifically intended for use with phosphate ester fluids and can be damaged by exposure to petroleum-based substances. This model features a fatigue rating of up to 5000 psi (350 bar) for the solenoid tube assembly and supports a maximum operating pressure of the same value. It has a flow capacity of up to 5 gpm (20 L/min) and allows for manual override with minimal force requirements. The floating style construction of the cartridge minimizes internal parts binding due to installation torque variations or machining discrepancies. For enhanced environmental protection, additional weatherized coils and kits are available, complementing the diverse coil connector options that offer ratings up to IP69K. The versatility in manual control setups and robust magnetic design ensures reliable valve shifting with high spool actuating force efficiency per Watt expended, making the Sun Hydraulics DMDASAN298 an effective solution for varied hydraulic system applications requiring moderate flow handling capabilities.

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.
