The Sun Hydraulics DMDASRV211 (DMDASRV211) 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 ensures precise control with its soft shift feature, which mitigates shock from valve actuation, although it is not recommended for applications requiring critical timing control. The soft shift model operates with a slower response time compared to standard solenoids, typically ranging from 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. This model boasts a manual override feature with a push-type control and is engineered with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. It is important to note that cartridges fitted with EPDM seals are intended for use with phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The wet armature design of the valve means that the working fluid surrounds the armature which might be susceptible to heat during prolonged energization periods. The DMDASRV211 also features an innovative magnetic design in the solenoid which enhances efficiency and reliability in valve shifting operations. Additionally, the unit supports various coil connector options compatible up to IP69K standards for environmental resilience. The construction incorporates Sun's floating style design which minimizes internal part binding due to installation or machining variances. This valve is suitable for systems requiring consistent performance under varying operational conditions and where environmental durability is critical. It offers an optimal balance of performance and reliability for specialized hydraulic applications.

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.
