The Sun Hydraulics DMDASBV928 (DMDASBV928) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic system applications requiring reliable directional control. This direct-acting, balanced spool valve features a unique soft shift functionality that minimizes hydraulic shock during valve actuation, which is particularly beneficial in systems where fluid dynamics can impact mechanical components and system stability. Although the soft shift model offers reduced performance limits compared to standard cartridges, it excels in applications where gentle ramping and reduced system shocks are more critical than precise timing control. The DMDASBV928 operates effectively within a flow capacity of 5 gpm (20 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve's manual override feature is push-type, allowing for temporary manual control of the valve position; however, it is not compatible with weatherized coils. The solenoid design incorporates a wet armature setup where the coil heat can affect the working fluid\u2014a consideration important in applications involving extended coil energization periods. Constructed with EPDM seals, this model is suitable for use with phosphate ester fluids but should avoid exposure to petroleum-based fluids to prevent seal damage. For environments requiring robust protection against harsh conditions, additional weatherized coils and kits are available. The DMDASBV928 also benefits from Sun\u2019s floating style construction which helps prevent internal parts binding due to installation torque or cavity/cartridge machining variations. This model's efficient magnetic design ensures high spool actuating force per watt expended, leading to reliable shifting even under varying operational conditions such as changes in flow, pressure, coil voltage, oil viscosity, and ambient temperature. Typical response times range from 150 ms to 300 ms depending on these factors. With its comprehensive design considerations and optional configurations for environmental resilience (IP69K rated coil connectors), the DMDASBV928 offers versatile integration into diverse hydraulic systems while maintaining consistent performance and durability.

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.
