The Sun Hydraulics DMDASAN223 (DMDASAN223) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies innovation in hydraulic system control components. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of up to 5 gpm (20 L/min). A notable feature of the DMDASAN223 is its soft shift functionality, which moderates hydraulic shock during valve actuation, thereby enhancing system longevity and reducing potential damage from sudden pressure spikes. However, it's important to note that this feature does not support critical timing applications, which would be better served by electro-proportional valves from Sun Hydraulics. The response time for this model varies between 150 ms to 300 ms, influenced by factors such as flow rate, pressure levels, coil voltage, oil viscosity, and ambient temperature conditions. For optimal performance of the soft shift feature, it is recommended that port 1 maintains a positive pressure. The valve also includes a push-type manual override control for added operational flexibility although it should be noted that other manual control options are not compatible with the soft shift feature but can be installed separately. Durability is assured with the solenoid tube assembly being fatigue rated for high-pressure service. The DMDASAN223 uses EPDM seals suitable for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. Additionally, the wet armature design means that heat from prolonged coil energization could affect fluid integrity over time. This model also incorporates Sun\u2019s floating style construction which minimizes internal binding risks due to installation torque or machining variations in cavity/cartridge assemblies.

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.
