The Sun Hydraulics DMDASBV628 (DMDASBV628) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool valve features a unique soft shift functionality, which moderates the shock typically associated with valve actuation, enhancing system longevity and reducing potential damage from hydraulic spikes. However, it is important to note that this soft shift feature is not suitable for applications requiring critical timing or precise ramping control; for such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASBV628 operates with a typical response time between 150 ms to 300 ms, influenced by factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It includes a push-type manual override control and boasts a fatigue rating for up to 5000 psi (350 bar), ensuring robust performance even under strenuous conditions. The valve's wet armature design allows the working fluid to cool the coil directly although prolonged energization can lead to fluid degradation in certain cases. Notably engineered with EPDM seals specifically for use with phosphate ester fluids, this model is incompatible with petroleum-based substances which could damage the seals. Its construction incorporates Sun's floating style design which minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. The DMDASBV628 supports various coil connector options with ratings up to IP69K for enhanced environmental protection against dust and water ingress. This model also offers additional weatherized coils and kits for further environmental safeguarding. With a capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), the DMDASBV628 provides reliable and efficient operation across a 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.
