The Sun Hydraulics DMDASPN612N (DMDASPN612N) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve features a unique soft shift capability, which is engineered to mitigate shock from valve actuation. Although the soft shift design increases the response time (typically between 150 ms to 300 ms), it enhances system smoothness compared to standard solenoid valves. The valve's soft shift performance requires port 1 to be maintained at positive pressure for optimal operation. It includes a push-type manual override control, and while other manual controls are not available with the soft shift feature, they can be installed in the field if necessary. However, it is important to note that manual override functionalities are incompatible with weatherized coils. Constructed with durability in mind, the solenoid tube assembly of this model is fatigue rated for service up to 5000 psi (350 bar). The DMDASPN612N uses EPDM seals suitable for phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. Additionally, its wet armature design means that heat generated by the coil affects the working fluid which could lead to breakdowns if the coil remains energized over extended periods. This valve also boasts a high efficiency solenoid that ensures reliable valve shifting by producing a strong spool actuating force per watt expended. For enhanced environmental protection, additional weatherized coil options and kits are available. The design incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Overall capacity of this model stands at 5 gpm (20 L/min) with maximum operating pressure reaching up to 5000 psi (350 bar). The compact yet robust construction of the DMDASPN612N makes it an ideal choice for systems requiring precise control and reliability 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.
