The Sun Hydraulics DMDASNV724N (DMDASNV724N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve features a unique soft shift functionality, which moderates the shock typically associated with valve actuation, though it is not suitable for applications requiring critical timing control. For scenarios demanding precise ramping or timing, alternative electro-proportional valves are recommended. The soft shift model offers a slower response time compared to Sun's standard solenoids, generally ranging from 150 ms to 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It should be noted that consistent performance from the soft shift feature requires port 1 to maintain positive pressure. This model includes a push-type manual override and is incompatible with other manual control options when configured with soft shift control; however, these can be added in the field if necessary. The valve\u2019s solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance even under high-pressure conditions. Designed with EPDM seals specifically for use with phosphate ester fluids, this valve must avoid exposure to petroleum-based substances which can damage the seals. The wet armature design means the working fluid surrounds the armature\u2014important to consider as prolonged energization can lead to heat build-up affecting certain fluid types. Additionally, the DMDASNV724N incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With maximum operating pressures of up to 5000 psi (350 bar) and flow capacities reaching 5 gpm (20 L/min), this valve is engineered for efficiency and reliability in demanding hydraulic systems.

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.
