The Sun Hydraulics DMDASAN828 (DMDASAN828) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency hydraulic system control. This direct-acting, balanced spool directional valve features a unique soft shift option that mitigates shock during valve actuation, making it suitable for applications sensitive to sudden changes in pressure but less ideal where precise timing control is crucial. For such scenarios, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASAN828 model boasts a response time ranging from 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It includes a push-type manual override control and is compatible with various manual control options that are easy to install in the field. However, it's important to note that the manual override functionality is not compatible with weatherized coils. Engineered with a wet armature design, the valve's working fluid surrounds the armature which can be exposed to heat if the coil remains energized over extended periods. This exposure may lead to breakdowns in certain fluids like water-glycol mixtures. The solenoid of the DMDASAN828 also features a high-efficiency magnetic design that ensures reliable valve shifting by generating a high spool actuating force per watt expended. This model incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar), and cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Overall, the Sun Hydraulics DMDASAN828 provides robust performance and flexibility for hydraulic systems requiring efficient flow control and shock mitigation without demanding precise timing controls.

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.
