The Sun Hydraulics DMDASNV223 (DMDASNV223) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve features a unique soft shift option that moderates the shock typically associated with valve actuation, enhancing system longevity and reducing potential damage from hydraulic shock. However, it is important to note that the soft shift feature may not be suitable for applications requiring critical timing or accurate ramping control; for such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASNV223 exhibits increased response times ranging from 150 ms to 300 ms compared to standard solenoids, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature conditions. The valve is engineered with a push-type manual override control and incorporates a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). It is essential that port 1 maintains positive pressure to ensure consistent performance of the soft shift functionality. This model utilizes EPDM seals specifically suited for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Its wet armature design means that the working fluid surrounds the armature which could lead to heat-related degradation of certain fluids over prolonged periods. The valve's efficient magnetic design ensures reliable spool actuation with high force per watt expended. Additional features include multiple coil connector options with ratings up to IP69K for enhanced environmental protection and Sun's floating style construction which minimizes internal part binding. This model has a maximum operating capacity of 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar), making it versatile for a broad range of hydraulic applications while ensuring robust performance and reliability.

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.
