The Sun Hydraulics DMDASRN612N (DMDASRN612N) is a high-efficiency solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve features soft shift capabilities, which help to minimize hydraulic shock during valve actuation. Although the soft shift model offers a slower response time compared to Sun's standard solenoids\u2014ranging between 150 ms to 300 ms\u2014it is beneficial in applications where reduced shock is more critical than timing precision. For applications requiring precise timing control, Sun recommends considering their electro-proportional valves instead. This model includes a push-type manual override and boasts a fatigue rating of 5000 psi (350 bar), making it robust for demanding applications. The valve\u2019s wet armature design means the working fluid surrounds the armature, which could lead to heat-related degradation of certain fluids over extended periods. Users should note that cartridges with EPDM seals are specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The DMDASRN612N also features a unique magnetic design that enhances the solenoid's efficiency and ensures reliable valve shifting with high spool actuating force per watt expended. The construction incorporates Sun\u2019s floating style to minimize internal parts binding due to excessive installation torque or cavity-cartridge machining variations. It supports a maximum operating pressure of 5000 psi (350 bar) and has options for weatherized coils and IP69K rated coil connectors for enhanced environmental protection. This model is particularly suited for systems where environmental resilience and reduced operational shock are prioritized.

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.
