The Sun Hydraulics DMDASAN912N (DMDASAN912N) is a solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its soft shift feature, which significantly reduces shock during valve actuation, although it should not be relied upon for critical timing applications. The soft shift model offers a slower response time compared to Sun's standard solenoids, typically ranging from 150 ms to 300 ms depending on various factors including flow, pressure, and ambient temperature. This model includes a push-type manual override and boasts a fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly. It is compatible with phosphate ester fluids when configured with EPDM seals but should avoid exposure to petroleum-based substances that could damage these seals. The wet armature design of the valve means that the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 5 gpm (20 L/min), and maximum leakage at 3000 psi not exceeding 5 in\u00b3/min. The manual override requires minimal force and has a short stroke distance for activation. The valve also features an IP69K rating for coil connectors, ensuring robust performance even in harsh environmental conditions. The construction utilizes Sun's floating style to minimize internal binding due to installation torque or machining variations of the cavity/cartridge. With its efficient magnetic design leading to high spool actuating force per Watt expended, this model ensures reliable shifting and operational longevity suitable for varied 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.
