The Sun Hydraulics DMDASBV848 (DMDASBV848) is a solenoid-operated, 3-way, 2-position cartridge valve designed for hydraulic applications requiring controlled motion and reliable performance. The valve features a direct-acting, balanced spool design which ensures stable operation even under varying conditions. The inclusion of a soft shift feature distinguishes this model by providing smoother transitions during valve actuation, thereby minimizing hydraulic shock. This feature is particularly beneficial in applications sensitive to sudden changes in pressure but is not suitable for scenarios where precise timing control is critical. This model's response time varies from 150 ms to 300 ms depending on several factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is recommended that port 1 maintains positive pressure to achieve consistent performance with the soft shift functionality. Additionally, the valve offers a push-type manual override control which does not support other manual control options when configured with soft shift control but can be modified with different manual controls in the field as necessary. Constructed for durability, the solenoid tube assembly of the DMDASBV848 is fatigue rated for up to 5000 psi (350 bar). The valve employs EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based fluids. A wet armature design allows the working fluid to surround the armature which may affect fluid integrity over extended periods of energization. For enhanced environmental protection and efficiency, various coil connector options provide ratings up to IP69K while additional weatherized coils are available separately. The design incorporates Sun\u2019s floating style construction minimizing internal part binding due to installation torque or machining variations of the cavity/cartridge. This model supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min), making it versatile for a wide range of hydraulic applications.

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.
