The Sun Hydraulics DMDASAN928 (DMDASAN928) is a solenoid-operated, 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This model is specifically designed with a soft shift feature to minimize hydraulic shock during valve actuation. Although this feature increases the valve's response time\u2014ranging from 150 ms to 300 ms\u2014it significantly enhances system smoothness by reducing the impact of sudden pressure changes. The valve operates optimally when port 1 maintains positive pressure. This model includes a push-type manual override control, which is not compatible with weatherized coils but can be replaced with other manual controls like T or D options in the field if the soft shift feature is not used. The solenoid tube assembly of this valve is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance even under high-pressure conditions. The DMDASAN928 uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. Its wet armature design means that the working fluid directly contacts the armature, potentially affecting fluid integrity if subjected to prolonged heat exposure. For electrical connectivity, several coil connector options are available, supporting up to IP69K ratings for enhanced environmental protection against dust and moisture ingress. The valve also incorporates Sun\u2019s floating style construction which helps prevent internal part misalignment or binding due to installation variances or excessive torque application. With a maximum flow capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), along with comprehensive design considerations for durability and performance adaptability, the Sun Hydraulics DMDASAN928 is engineered for reliable operation in diverse hydraulic applications requiring moderated flow and pressure handling capabilities.

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.
