The Sun Hydraulics DMDASBN211 (DMDASBN211) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a unique soft shift mechanism that significantly reduces hydraulic shock during valve actuation. Although this soft shift feature increases response time, typically ranging from 150 ms to 300 ms, it enhances system longevity by minimizing the impact of sudden pressure changes. The valve is especially suited for environments where reduced shock is beneficial but not critical for timing-sensitive operations. Constructed with a wet armature design, the DMDASBN211 ensures that the working fluid surrounds the armature, which helps in heat management when the coil is energized over extended periods. The solenoid of this valve boasts a high-efficiency magnetic design that delivers strong spool actuating force per watt expended, ensuring reliable and consistent valve shifting. This model also includes a push-type manual override control and features an innovative floating style construction that minimizes internal part binding due to installation torque or machining variations. Rated for up to 5000 psi (350 bar) and capable of handling flow rates up to 5 gpm (20 L/min), the DMDASBN211 is designed to meet rigorous operational demands. It incorporates EPDM seals suitable for phosphate ester fluids while being incompatible with petroleum-based fluids which can degrade these seals. Additionally, coil connector options provide protection ratings up to IP69K with additional weatherized coils available for enhanced environmental resilience. Ideal for use in various hydraulic systems requiring dependable directional control and shock mitigation, this valve integrates seamlessly into existing setups thanks to its standard cavity size T11A and compatibility with various manual override controls not initially included with soft shift models.

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.
