The Sun Hydraulics DMDASAV211 (DMDASAV211) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation. Although it enhances the smooth operation by increasing the response time (ranging from 150 ms to 300 ms), it is not suitable for applications requiring precise timing or ramp control, where electro-proportional valves might be better suited. The DMDASAV211 is designed with a manual override control and is compatible with various manual control options which can be installed in the field. However, its weatherized coils are not compatible with this manual override functionality. The cartridge's solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. For optimal performance, port 1 should maintain positive pressure. The valve's seals are made from EPDM, suitable for use with phosphate ester fluids but vulnerable to petroleum-based fluids which can cause damage. Additionally, this model incorporates a wet armature design where the working fluid surrounds the armature; prolonged energization of the coil could lead to breakdown of certain fluids like water-glycol mixtures. Sun Hydraulics has equipped this model with a high-efficiency solenoid that delivers strong spool actuating force per Watt expended, ensuring reliable shifting of the valve. The construction utilizes Sun's floating style to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. This model supports a flow capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures of 5000 psi (350 bar). It also features different coil connector options rated up to IP69K for enhanced environmental protection against dust and moisture ingress.

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.
