The Sun Hydraulics DMDASNN224N (DMDASNN224N) is a solenoid-operated 3-way, 2-position cartridge that serves as a direct-acting, balanced spool directional valve. This model is designed with a soft shift feature to mitigate shock from valve actuation, enhancing operational smoothness, although it is not suitable for applications requiring precise timing control. With typical response times ranging from 150 ms to 300 ms, this valve's performance can vary based on factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASNN224N includes a push-type manual override and features a solenoid tube assembly rated for up to 5000 psi (350 bar). It is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. The valve's wet armature design means the working fluid surrounds the armature which could lead to breakdowns in certain fluid types if the coil remains energized for extended periods. Furthermore, the unique magnetic design of the solenoid ensures high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. The construction employs Sun\u2019s floating style technique to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Additional features include an array of coil connector options with ratings up to IP69K for enhanced environmental protection. This model also supports various manual control options that can be installed in the field despite not being orderable with soft shift controls. It is essential for consistent performance that port 1 maintains positive pressure.

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.
