The Sun Hydraulics DMDASPV828 (DMDASPV828) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is particularly notable for its soft shift capability, which significantly reduces shock during valve actuation, making it ideal for applications sensitive to sudden changes in pressure or flow. However, it is advised not to rely solely on this feature in scenarios where precise timing control is essential; for such needs, electro-proportional valves may be more appropriate. The DMDASPV828 supports a flow capacity up to 5 gpm (20 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It includes a push-type manual override control and boasts an enhanced response time ranging from 150 ms to 300 ms depending on various factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, it's recommended that port 1 maintains positive pressure. This model also incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or variations in cavity/cartridge machining. The solenoid tube assembly of the DMDASPV828 is fatigue rated for high-pressure service and the valve utilizes wet armature design which could influence fluid characteristics if the coil remains energized extensively. Moreover, the DMDASPV828 comes with several coil connector options offering up to IP69K ratings for enhanced environmental protection. It is also compatible with EPDM seals suitable for systems using phosphate ester fluids but not with petroleum-based fluids as they can damage the seals. With its robust magnetic design and efficient solenoid operation yielding high spool actuating force per watt expended, this valve ensures reliable performance across various applications without excessive energy consumption.

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.
