The Sun Hydraulics DMDASAN224 (DMDASAN224) 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 option that moderates the shock typically associated with valve actuation, making it suitable for systems where minimizing hydraulic shock is essential. However, it's important to note that this soft shift feature may not be ideal for applications demanding precise timing control, such as those requiring accurate ramping. The valve boasts a response time ranging from 150 ms to 300 ms, depending on various factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, it is recommended that port 1 maintains positive pressure. A distinctive aspect of this model is its manual override functionality which includes a push-type control. It should be noted that while other manual controls can be added in the field, they are not compatible with weatherized coils. Constructed to handle pressures up to 5000 psi (350 bar), the DMDASAN224 is fatigue rated for rigorous use. The valve features EPDM seals suited for phosphate ester fluids but should avoid exposure to petroleum-based fluids which can degrade these seals. Additionally, its wet armature design implies that the working fluid surrounds the armature which could lead to heat-related degradation of certain fluid types over extended periods. This model also incorporates Sun\u2019s floating style construction which reduces the risk of internal parts binding due to improper installation torque or machining variations in the cavity/cartridge interface. With options for IP69K rated coil connectors and additional weatherized coil kits available for enhanced environmental protection, this valve adapts well to varying operational environments while maintaining 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.
