The Sun Hydraulics DMDASBN71219 (DMDASBN71219) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve engineered for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve is designed with unique features to enhance system performance and reliability. It includes a soft shift feature that moderates the shock typically associated with valve actuation, which is particularly beneficial in reducing system stresses though it should not be relied upon for applications requiring critical timing. The valve's soft shift design significantly increases response times, typically ranging from 150 ms to 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, port 1 should maintain a positive pressure. The valve also boasts a manual override control which is push-type; however, it should be noted that weatherized coil options are not compatible with this manual override functionality. Constructed to be robust under high pressures, the solenoid tube assembly of this model is fatigue rated for service up to 5000 psi (350 bar). It utilizes EPDM seals suitable for phosphate ester fluids but these seals must avoid exposure to petroleum-based substances to prevent damage. Additionally, the wet armature design means that the working fluid surrounds the armature which could lead to heat-related degradation of certain fluids over extended periods. The DMDASBN71219 utilizes Sun\u2019s floating style construction that minimizes internal part binding due to installation torque or variations in cavity/cartridge machining. Its efficient magnetic design ensures high spool actuating force per watt expended which enhances reliable shifting of the valve. With options for coils rated up to IP69K and additional kits for environmental protection available, this model adapts well to various operational environments ensuring durability and consistent performance under diverse 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.
