The Sun Hydraulics DMDASBN548 (DMDASBN548) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve offers unique capabilities, particularly beneficial in applications where shock reduction due to valve actuation is crucial. The soft shift feature of this model significantly increases response times ranging from 150 ms to 300 ms depending on various factors such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. It's essential to maintain port 1 at positive pressure for consistent performance. The DMDASBN548 is equipped with a push-type manual override control and features a wet armature design where the working fluid surrounds the armature. This design consideration is vital as it can affect the fluid's integrity if the coil remains energized for extended periods. Additionally, the solenoid tube assembly of this model is fatigue rated for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Notably, this valve incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. The cartridge also supports various coil connector options with ratings up to IP69K for environmental protection. Its robust magnetic design ensures high efficiency and reliable valve shifting by generating significant spool actuating force per Watt expended. The DMDASBN548 has a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min). It features minimal leakage and comes in a compact form factor with a weight of only 0.60 lb (0.30 kg), making it suitable for various industrial applications requiring precise fluid control with enhanced shock reduction capabilities.

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.
