The Sun Hydraulics DMDASPN211 (DMDASPN211) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve is notable for its soft shift feature, which moderates the shock typically associated with valve actuation. Although this feature slows response times (typically ranging from 150 ms to 300 ms), it is particularly beneficial in reducing system shocks. However, it is not recommended for applications requiring critical timing or accurate ramping; for such needs, electroproportional valves might be more suitable. The DMDASPN211 model incorporates a push-type manual override control and boasts a robust solenoid tube assembly rated for up to 5000 psi (350 bar). It is essential to note that cartridges with EPDM seals are intended specifically for systems using phosphate ester fluids and should not be exposed to petroleum-based substances. The wet armature design of the valve means that the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods. This model also features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The manual override functionality of this model does not support weatherized coils, but other manual control options can be added in the field if necessary. For environmental protection, additional weatherized coils and kits are available. The coil connector options can handle ratings up to IP69K. With a maximum operating pressure of 5000 psi and a capacity of 5 gpm (20 L/min), this valve is designed for high-performance applications requiring reliable shifting and control of hydraulic fluids under varying operational conditions.

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.
