The Sun Hydraulics DMDASAN524 (DMDASAN524) is a solenoid-operated 3-way, 2-position cartridge valve that operates as a direct-acting, balanced spool directional valve. This model features a \"soft shift\" design, which is intended to reduce the shock typically associated with valve actuation. While this feature can significantly increase the response time\u2014with typical ranges between 150 ms to 300 ms\u2014it should not be relied upon in applications where precise timing control is critical. For such needs, electroproportional valves may be more appropriate. The soft shift valve is interchangeable with standard cartridges but exhibits lower performance limits. It requires port 1 to maintain positive pressure for consistent performance and includes a push-type manual override control. Notably, other manual controls like T or D options are not compatible with the soft shift feature but can be installed in the field if necessary. The physical construction of this valve includes Sun's floating style design which helps minimize internal part binding due to installation torque or cavity/cartridge machining variations. The solenoid tube assembly of the DMDASAN524 is fatigue rated for service up to 5000 psi (350 bar), making it robust for high-pressure applications. Additionally, it utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals are vulnerable to damage from exposure to petroleum-based products. With a maximum operating capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), this model ensures efficient operation under demanding conditions. The solenoid\u2019s unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended, thereby ensuring reliable valve shifting even under varied environmental conditions. Options for coil connectors that offer up to IP69K ratings are available, providing further adaptability and protection in different operational environments.

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.
