The Sun Hydraulics DMDASAV297 (DMDASAV297) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency hydraulic system control. This direct-acting, balanced spool directional valve features a unique soft shift mechanism that minimizes hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage to other hydraulic components. Although the soft shift model offers a slower response time ranging from 150 ms to 300 ms compared to standard solenoid valves, it is particularly useful in applications where smooth transitions are more critical than timing precision. Equipped with a manual override feature, the DMDASAV297 allows for manual operation in case of an electrical power failure; however, this functionality is not compatible with weatherized coils. The valve\u2019s construction includes Sun\u2019s floating style design which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. This model is configured to work optimally within a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). It also features EPDM seals suitable for systems using phosphate ester fluids while being incompatible with petroleum-based fluids which could damage the seals. The solenoid tube assembly of the DMDASAV297 is fatigue rated for robust performance under high-pressure conditions. For environmental protection and enhanced durability in harsh conditions, additional weatherized coil options and kits are available. The coil connector options can withstand ratings up to IP69K, ensuring reliable operation even when exposed to high degrees of moisture and dust. This versatility makes the DMDASAV297 an excellent choice for diverse hydraulic applications requiring reliable directional control and fluid compatibility.

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.
