The Sun Hydraulics DMDASNN212 (DMDASNN212) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. Featuring a direct-acting, balanced spool design, this model ensures stable and reliable operation under different conditions. The valve is particularly noted for its soft shift feature, which significantly reduces shock during valve actuation. Although this feature delays response times (typically between 150 ms to 300 ms), it makes the valve suitable for applications where shock minimization is more critical than timing precision. The DMDASNN212 operates optimally when port 1 maintains a positive pressure and includes a push-type manual override control for additional operational flexibility. However, it should be noted that other manual control options are not compatible with the soft shift feature but can be added later if required. The valve's construction incorporates Sun's floating style to prevent internal parts from binding due to excessive installation torque or cavity/cartridge machining variations. Designed with a wet armature setup, the DMDASNN212 allows the working fluid to surround the armature, which could be a consideration if the coil remains energized over extended periods as some fluids may degrade at elevated temperatures. The solenoid tube assembly of this model is fatigue rated for up to 5000 psi (350 bar), ensuring durability and long service life in demanding environments. Seal options include EPDM for systems using phosphate ester fluids, though exposure to petroleum-based fluids should be avoided as it can damage these seals. Additionally, the model offers various coil connector options with ratings up to IP69K for enhanced environmental protection against dust and moisture ingress. This makes the DMDASNN212 an adaptable solution suitable for a wide range of industrial applications requiring robust performance and reliability in hydraulic fluid direction control.

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.
