The Sun Hydraulics DMDASBV248 (DMDASBV248) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. It features a direct-acting, balanced spool directional valve mechanism which ensures stable and reliable control of fluid flow. This model is particularly noted for its soft shift capability, which significantly reduces shock during valve actuation, although it is not suitable for applications where precise timing control is critical. For such needs, Sun Hydraulics recommends considering their electro-proportional valves. The DMDASBV248 includes a push-type manual override control and has been designed to be interchangeable with standard cartridges while offering softer shift performance with increased response times ranging typically from 150 ms to 300 ms. This response time can vary based on factors such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. The valve's construction incorporates Sun's floating style design to minimize internal part binding due to installation torque or machining variations in the cavity/cartridge. Constructed to handle maximum operating pressures up to 5000 psi (350 bar) and flow capacities up to 5 gpm (20 L/min), the DMDASBV248 features robust durability with its solenoid tube assembly fatigue rated for high-pressure service. It also includes options for EPDM seals suited for phosphate ester fluids but incompatible with petroleum-based fluids which could damage the seals. This model also offers various coil connector options with ratings up to IP69K for enhanced environmental protection against harsh conditions. The manual override feature demands an actuation force of about 5 lbs at 1000 psi at port 1 and allows a stroke of .10 inches (2.5 mm). The overall weight of the model is modest at .60 lb (0.30 kg), making it suitable for various installation environments without adding significant bulk.

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.
