The Sun Hydraulics DMDASAN548 (DMDASAN548) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve stands out with its soft shift feature which moderates the shock typically associated with valve actuation. Although this feature slows the response time to between 150 ms and 300 ms, it significantly reduces system shocks, making it ideal for applications sensitive to sudden movements but not suitable for scenarios where exact timing is crucial. Constructed for robust performance, the DMDASAN548 valve supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). It incorporates a push-type manual override control and is designed with a wet armature setup, meaning the armature is immersed in fluid which can be a consideration if the coil remains energized over extended periods. This model uses EPDM seals recommended for systems using phosphate ester fluids; however, these seals are vulnerable to damage from exposure to petroleum-based products. For installation flexibility, the valve features Sun\u2019s floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. Its solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability in demanding environments. Additional options include various coil connector configurations with ratings up to IP69K for enhanced environmental protection. The manual override functionality of this model does not support weatherized coils, thus requiring consideration based on the operating environment. Overall, the Sun Hydraulics DMDASAN548 offers an efficient and adaptable solution for controlled hydraulic operations across various 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.
