The Sun Hydraulics DMDASRN211 (DMDASRN211) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically engineered to offer soft shift capabilities, which help in minimizing the hydraulic shock typically associated with valve actuation. Although it shares interchangeability with standard cartridges, the DMDASRN211 has performance limits tailored for applications where lower shock levels are preferable over rapid actuation times. With a typical response time ranging from 150 ms to 300 ms, it is not recommended for applications where precise timing control is crucial. The valve operates optimally when port 1 maintains positive pressure and incorporates a push-type manual override control, enhancing its versatility in manual operations. However, it's important to note that this manual override feature is not compatible with weatherized coils. The DMDASRN211 also boasts a fatigue rating for up to 5000 psi (350 bar) service in its solenoid tube assembly and utilizes EPDM seals suitable for systems using phosphate ester fluids. A unique aspect of this model is its wet armature design; the working fluid surrounds the armature which can be significant if the coil remains energized for extended periods, potentially affecting fluid integrity in certain conditions. Additionally, its magnetic design ensures high efficiency and reliable valve shifting due to the powerful spool actuating force per watt expended. For environmental protection and durability under various conditions, the coil connector options are rated up to IP69K. Moreover, the valve\u2019s construction features Sun\u2019s floating style which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. This model has a flow capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar).

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.
