The Sun Hydraulics DMDASRN912N (DMDASRN912N) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve is engineered to effectively control the direction of fluid flow in various hydraulic applications. Featuring a soft shift option, the DMDASRN912N mitigates shock caused by valve actuation, although it is not suitable for applications requiring precise timing control, where electro-proportional valves might be preferable. The valve's soft shift feature increases response time compared to standard solenoid valves offered by Sun Hydraulics, with typical response times ranging from 150 ms to 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is important that port 1 maintains positive pressure for consistent performance of the soft shift mechanism. Additionally, this model includes a push-type manual override control and incorporates a wet armature design where the working fluid surrounds the armature. This design aspect should be considered in applications where the coil remains energized for extended periods as it can lead to breakdowns in certain fluid types. Constructed with durability in mind, the solenoid tube assembly of the DMDASRN912N is fatigue rated for up to 5000 psi (350 bar). The valve also features EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Furthermore, this model showcases Sun Hydraulics' floating style construction which minimizes internal part binding due to installation torque or machining variations of the cavity/cartridge. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 5 gpm (20 L/min), and an IP69K rating available through specific coil connector options for enhanced environmental protection. The DMDASRN912N weighs approximately 0.60 lb (0.30 kg) and offers various manual override options that can be field installed except when combined with weatherized coils.

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.
