The Sun Hydraulics DMDASNN71219 (DMDASNN71219) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option to mitigate the shock typically associated with valve actuation. Although this feature slows the response time (ranging from 150 ms to 300 ms), it enhances system longevity by reducing the impact of sudden pressure changes. The valve is particularly suited for applications where shock reduction is more critical than timing precision, as its soft shift mechanism does not offer the precise ramping or timing control available with electro-proportional valves. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 5 gpm (20 L/min), the DMDASNN71219 is robust enough for demanding applications. It includes a push-type manual override and features an innovative magnetic design that optimizes efficiency by maximizing spool actuating force per watt expended. This ensures reliable shifting even under challenging conditions. The construction of the DMDASNN71219 incorporates Sun\u2019s floating style design which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. This design consideration enhances overall durability and performance reliability. Additionally, it has been fatigue rated for intense operational demands. For environmental resilience, this model offers various coil connector options with ratings up to IP69K and can be fitted with additional weatherized coils for enhanced protection against harsh conditions. The cartridge also supports EPDM seals suitable for phosphate ester fluids, though exposure to petroleum-based fluids should be avoided as it may damage the seals. Overall, the Sun Hydraulics DMDASNN71219 provides a versatile and durable solution for hydraulic system control where moderate flow rate and high-pressure handling are required alongside enhanced operational smoothness due to its soft shift feature.

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.
