The Sun Hydraulics DMDASBV748 (DMDASBV748) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This model is specifically engineered for applications requiring reliable directional control of hydraulic fluids. The valve offers a soft shift feature which significantly reduces hydraulic shock during valve actuation, although it is not recommended for applications where precise timing control is crucial. For such needs, Sun Hydraulics suggests considering their electro-proportional valves instead. The DMDASBV748 operates with a typical response time ranging from 150 ms to 300 ms, influenced by factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is designed to work optimally when port 1 maintains positive pressure. Notably, this model includes a push-type manual override control and features various manual control options that can be easily installed in the field if required\u2014though it's important to note that these are not compatible with weatherized coils. This model is constructed with durability in mind; its solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar). The DMDASBV748 uses EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based substances which could damage the seals. Additionally, the valve incorporates Sun\u2019s floating style construction to minimize internal binding due to installation torque or machining variations. The valve's high efficiency magnetic design ensures reliable shifting with minimal energy expenditure. It also supports various coil connector options with ratings up to IP69K for enhanced environmental protection. With a maximum operating capacity of 5 gpm (20 L/min) and an installation torque between 30-35 lbf\u00b7ft (41-47 Nm), the DMDASBV748 combines robust performance with versatile application potential in fluid power systems.

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.
