The Sun Hydraulics DMDASRV212N (DMDASRV212N) is a solenoid-operated 3-way, 2-position cartridge valve designed for efficient hydraulic flow control. This direct-acting, balanced spool directional valve features a unique soft shift functionality that minimizes hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage from sudden pressure spikes. However, it's important to note that the soft shift feature does not support critical timing applications; for such needs, Sun Hydraulics recommends considering their electroproportional valves instead. The DMDASRV212N operates with typical response times ranging from 150 ms to 300 ms, dependent on variables such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is built to ensure consistent performance with port 1 maintained at positive pressure. The valve also includes a push-type manual override control but is incompatible with weatherized coils when using this functionality. Constructed to handle pressures up to 5000 psi (350 bar), the valve's solenoid tube assembly is fatigue rated for demanding applications. It incorporates Sun's floating style construction which helps prevent internal part binding caused by excessive installation torque or cavity/cartridge machining discrepancies. The DMDASRV212N uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Additionally, the design features a wet armature setup where the working fluid surrounds the armature exposed to heat from the coil\u2014important to consider in applications where the coil remains energized over extended periods. This model also supports an IP69K rating for coil connectors and offers options for enhanced environmental protection with additional weatherized coils and kits available. The cartridge ensures high efficiency and reliable valve shifting due to its advanced magnetic design which generates significant spool actuating force per watt expended.

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.
