The Sun Hydraulics DMDASNN712N (DMDASNN712N) is a solenoid-operated, 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is equipped with a soft shift feature designed to minimize hydraulic shock during valve actuation. Although beneficial for reducing system shocks, it is not suitable for applications requiring precise timing control, where electroproportional valves might be more appropriate. The soft shift model has a slower response time compared to standard solenoids, typically ranging from 150 ms to 300 ms depending on various factors such as flow rate and oil viscosity. The valve supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). It includes EPDM seals intended for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. A notable feature of this model is the wet armature design, where the working fluid surrounds the armature which can lead to fluid breakdown in prolonged energized states. Additionally, the DMDASNN712N incorporates Sun's floating style construction that helps prevent internal part binding due to installation errors or cavity/cartridge machining variations. It also provides manual override functionality with a push-type control but is incompatible with weatherized coils. For environmental protection in harsh conditions, specific weatherized coils and kits are available separately. This valve's robust design includes options for coil connectors rated up to IP69K for enhanced durability against environmental elements. With its unique magnetic design, the solenoid offers high efficiency and reliable spool actuating force per watt expended. This makes the DMDASNN712N an effective solution for various hydraulic applications requiring moderate flow control and shock reduction capabilities.

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.
