The Sun Hydraulics DMDASNV224 (DMDASNV224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a unique soft shift option that moderates the speed and force of the valve actuation, effectively minimizing hydraulic shock. This characteristic is particularly beneficial in systems where sudden changes in pressure could potentially cause mechanical stresses or operational issues, although it is not suitable for applications requiring precise timing control. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), this valve is built to handle demanding tasks. The soft shift model operates with increased response times ranging from 150 ms to 300 ms compared to standard models, depending on variables such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature conditions. The DMDASNV224 includes a manual override feature with a push-type control mechanism. It should be noted that while other manual control options are available, they cannot be combined with the soft shift feature but can be installed separately if needed. The design also incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Another notable design aspect of the DMDASNV224 is its wet armature solenoid configuration which helps enhance efficiency by increasing spool actuating force per watt expended. This high efficiency ensures reliable shifting performance even under varied environmental conditions. The solenoid assembly itself is fatigue rated for consistent performance under high-pressure operations. This valve also benefits from Sun Hydraulics' floating style construction which reduces the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining discrepancies. Overall, the DMDASNV224 offers an effective solution for managing directional control in hydraulic systems while providing additional features that enhance operational stability and component longevity.

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.
