The Sun Hydraulics DMDASBV948 (DMDASBV948) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency hydraulic applications. This direct-acting, balanced spool directional valve features a soft shift option that minimizes hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage to sensitive components. However, it is important to note that the soft shift feature increases response times (150 ms to 300 ms), which may not be suitable for applications requiring precise timing control. The valve is engineered with a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as it can affect fluid integrity if the coil remains energized for extended periods, particularly with water-glycol mixtures which might degrade and form varnishes. The DMDASBV948 includes a push-type manual override control and features a fatigue rating of 5000 psi (350 bar) for its solenoid tube assembly. It also incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation torque or machining variations. For environmental durability, the valve offers coil connector options rated up to IP69K and compatibility with additional weatherized coils and kits for enhanced protection. Configurations with EPDM seals are tailored for systems using phosphate ester fluids; however, these should not be exposed to petroleum-based fluids as they could damage the seals. The DMDASBV948 valve supports a flow capacity of up to 5 gpm (20 L/min) and can operate at pressures up to 5000 psi (350 bar). Notably, it maintains minimal leakage at high pressures, ensuring efficient operation. This model's robust construction coupled with innovative design features makes it an excellent choice for various hydraulic applications requiring reliable performance and flexibility in harsh environments.

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.
