The Sun Hydraulics DMDASAV824 (DMDASAV824) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a unique soft shift functionality that moderates the shock typically associated with valve actuation. The soft shift model is interchangeable with standard cartridges but is optimized for lower performance limits and should not be used where timing is critical\u2014instead, electro-proportional valves would be more suitable. The valve's response time varies between 150 ms to 300 ms depending on factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. To achieve consistent performance from the soft shift feature, it is recommended that port 1 maintains positive pressure. Additionally, this model includes a push-type manual override control; however, other manual controls like T or D are incompatible with the soft shift feature but can be added in the field. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of the DMDASAV824 is fatigue rated for high-pressure applications. The wet armature design means that heat generated by the coil directly affects the working fluid which could degrade certain types of hydraulic fluids over time. This model uses EPDM seals specifically for systems using phosphate ester fluids and should avoid exposure to petroleum-based fluids which could damage these seals. This valve also boasts a high-efficiency solenoid design that provides strong spool actuating force per watt expended ensuring reliable operation. The DMDASAV824 incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With an array of coil connector options offering up to IP69K ratings and additional weatherized coils available, this model adapts well to various environmental conditions ensuring robust and reliable performance in diverse applications.

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.
