The Sun Hydraulics DMDASPV248 (DMDASPV248) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for advanced hydraulic system applications. This direct-acting, balanced spool directional valve features a unique soft shift capability that significantly reduces shock during valve actuation, enhancing system longevity and reducing potential damage to mechanical components. Notably, the soft shift model offers increased response times ranging from 150 ms to 300 ms compared to standard solenoid models, dependent on various factors including flow, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASPV248 is engineered with a push-type manual override control and is compatible with EPDM seals for use in systems utilizing phosphate ester fluids. It is important to note that exposure to petroleum-based fluids can damage the seals. The valve\u2019s design incorporates a wet armature setup where the working fluid surrounds the armature. This design consideration is crucial as it can influence fluid integrity if the coil remains energized over extended periods. For environmental protection and enhanced performance reliability under diverse conditions, the DMDASPV248 offers coil connector options with ratings up to IP69K and additional weatherized coils are available. Its construction utilizes Sun\u2019s floating style approach to minimize internal parts binding due to installation torque or cavity-cartridge machining variations. This model supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min), making it suitable for a broad range of hydraulic applications where precise control and reliability are required. The manual override feature requires minimal force, ensuring ease of operation under different pressure settings. This robust valve configuration marks it as an essential component for systems requiring dependable performance with an option for manual intervention in operational procedures.

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.
