The Sun Hydraulics DMDASRN612 (DMDASRN612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a unique soft shift design that moderates the shock typically associated with valve actuation. Although it offers a slower response time ranging from 150 ms to 300 ms, which varies based on flow, pressure, coil voltage, oil viscosity, and ambient temperature, it ensures smoother transitions and reduced system shocks. Engineered for versatility and reliability, the DMDASRN612 includes a push-type manual override control and boasts an impressive fatigue rating for service up to 5000 psi (350 bar). It incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. Additionally, the valve is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Its wet armature design means the working fluid surrounds the armature which can lead to heat buildup if the coil remains energized over long durations. This may degrade certain types of hydraulic fluids. For enhanced durability and environmental protection in harsh conditions, there are options for weatherized coils and kits that adhere to IP69K standards. The DMDASRN612 is also designed with ease of field maintenance in mind\u2014manual control options like TwistLock can be easily added later as needed. Overall, this model is an excellent choice for applications requiring reliable shifting performance where moderate response times and reduced shock levels are beneficial. It provides robust operation with a variety of manual override and sealing options to suit different environmental requirements and fluid types.

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.
