The Sun Hydraulics DMDASNV228 (DMDASNV228) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency hydraulic control. This direct-acting, balanced spool directional valve stands out for its soft shift feature which minimizes hydraulic shock during valve actuation. Although it enhances the smooth operation, it is not suitable for applications requiring precise timing control, such as those needing exact ramping or timing adjustments. For such applications, Sun Hydraulics recommends their electro-proportional valves. This model offers a response time ranging from 150 ms to 300 ms, varying with flow rate, pressure levels, coil voltage, oil viscosity, and ambient temperatures. Installation flexibility is provided by the push-type manual override control included with this valve; however, it's important to note that this manual functionality is incompatible with weatherized coils. The DMDASNV228 features a robust design with its solenoid tube assembly being fatigue rated for up to 5000 psi (350 bar). It employs EPDM seals suitable for phosphate ester fluids but vulnerable to petroleum-based substances which can degrade these seals. The wet armature design of the valve ensures that the working fluid surrounds the armature\u2014important when considering fluid types as some may degrade under prolonged exposure to heat. For environmental resilience, additional weatherized coils and kits are available enhancing the valve\u2019s suitability across various operating conditions. Its unique magnetic design contributes significantly to high spool actuating force per watt expended ensuring reliable performance and shifting of the valve. This model also incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to variations in installation torque or cavity/cartridge machining discrepancies. With a maximum flow capacity of 5 gpm (20 L/min) and an ability to handle pressures up to 5000 psi (350 bar), this compact yet powerful hydraulic component is essential for efficient fluid power operations in various mechanical setups where smooth and controlled movement is critical.

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.
