The Sun Hydraulics DMDASBN612 (DMDASBN612) is a solenoid-operated 3-way, 2-position cartridge valve that offers advanced hydraulic control with its direct-acting, balanced spool design. This model features a unique soft shift option that mitigates shock from valve actuation, enhancing system longevity and reducing noise. However, it is important to note that this soft shift feature may increase response times (typically between 150 ms to 300 ms), which could affect applications where precise timing is critical. For such scenarios, Sun Hydraulics suggests considering their electro-proportional valves instead. Constructed for robust performance, the DMDASBN612 includes a push-type manual override and boasts a fatigue rating of 5000 psi (350 bar). It is designed with a wet armature setup where the working fluid surrounds the armature\u2014important for users to consider as prolonged energization can heat the fluid and potentially lead to breakdowns in certain types of fluids like water-glycol mixtures. This model supports flow rates up to 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). It also features IP69K rated coil connector options for enhanced environmental protection against dust and high-temperature water jets. The valve\u2019s construction incorporates Sun\u2019s floating style design which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. For applications requiring compatibility with phosphate ester fluids, cartridges configured with EPDM seals are available, although these should not be exposed to petroleum-based substances which can damage the seals. Overall, the DMDASBN612 is engineered for reliable shifting and efficient performance across various hydraulic applications.

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.
