The Sun Hydraulics DMDASNN212N (DMDASNN212N) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-efficiency hydraulic system applications. This direct-acting, balanced spool directional valve features a unique soft shift control which moderates the shock typically associated with valve actuation. Although it offers smoother transitions and can significantly increase response times (ranging from 150 ms to 300 ms depending on various factors like flow and pressure), it is not suitable for applications where precise timing control is critical. For such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. This model incorporates a wet armature design, meaning the working fluid not only lubricates but also cools the armature. It\u2019s important to note that long periods of coil energization can lead to higher fluid temperatures which might degrade certain types of hydraulic fluids. The valve is designed with durability in mind, featuring a fatigue rating for up to 5000 psi (350 bar) service and includes EPDM seals suitable for phosphate ester-based fluids; however, these seals are vulnerable to damage by petroleum-based products. The DMDASNN212N also boasts manual override capabilities with a push-type control, although alternative manual controls are not compatible with the soft shift feature but can be installed separately. It supports a maximum operating pressure of 5000 psi (350 bar), and its flow capacity reaches up to 5 gpm (20 L/min). The solenoid's robust magnetic design ensures high efficiency and reliable valve shifting with minimal power consumption. Additionally, this model benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge setup. This makes the DMDASNN212N an adaptable solution suitable for various hydraulic system applications requiring reliable performance under varying operational conditions.

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.
