The Sun Hydraulics DMDASNV928 (DMDASNV928) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a soft shift option which minimizes hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage to sensitive components. However, it should be noted that the soft shift feature increases response times (typically between 150 ms to 300 ms), which may not be suitable for applications requiring critical timing or fast actuation. The DMDASNV928 valve is capable of handling maximum operating pressures up to 5000 psi (350 bar) and has a flow capacity of 5 gpm (20 L/min). It incorporates a wet armature design where the working fluid surrounds the armature, which could affect performance if the coil remains energized for extended periods due to heat exposure that can degrade certain fluid types. The valve's construction uses Sun\u2019s floating style design to prevent internal parts from binding due to installation torque or machining variations. This model also includes a push-type manual override control, though it is not compatible with weatherized coils. The manual override requires an actuation force of about 5 lbs at 1000 psi on Port 1 and has a stroke length of .10 inches (2.5 mm). Additionally, this valve offers various coil connector options with protection ratings up to IP69K for enhanced environmental resistance. Seals made from EPDM in this cartridge are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids can cause damage. The solenoid\u2019s innovative magnetic design ensures efficient power usage while providing strong spool actuating force, leading to reliable operation under diverse conditions. This model's robust build and versatile features make it suitable for a wide range of hydraulic applications requiring controlled movement and reliable performance under high-pressure 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.
