The Sun Hydraulics DMDASAV4E12V (DMDASAV4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve features a unique soft shift option that moderates the shock typically associated with valve actuation, enhancing system longevity and reducing potential damage from hydraulic spikes. Although the soft shift model offers a slower response time ranging from 150 ms to 300 ms compared to standard solenoid valves, it is advantageous in applications where smooth transitions are more critical than timing precision. The valve operates efficiently under a maximum pressure of 5000 psi (350 bar) and can handle flow capacities up to 5 gpm (20 L/min). It includes a push-type manual override control, which provides an additional layer of operational security and flexibility. Notably, this manual override feature is not compatible with weatherized coils, which are available for enhanced environmental protection. The robust construction of the solenoid tube assembly ensures fatigue resistance up to the rated pressure. Designed with EPDM seals specifically for use with phosphate ester fluids, the DMDASAV4E12V must avoid exposure to petroleum-based substances to prevent seal damage. Its wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity if exposed to prolonged heat. The valve's magnetic design boosts efficiency by maximizing spool actuating force per watt expended. Furthermore, Sun Hydraulics incorporates floating style construction into this model to minimize internal part binding due to installation torque or machining variations in the cavity/cartridge setup. This thoughtful engineering ensures reliable and consistent performance across various hydraulic 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.
