The Sun Hydraulics DMDASNN2E12V (DMDASNN2E12V) is a solenoid-operated 3-way, 2-position cartridge valve designed for versatile hydraulic system applications. This direct-acting, balanced spool directional valve offers a soft shift feature that mitigates shock from valve actuation, enhancing system longevity and reducing potential damage from hydraulic spikes. Although the soft shift model provides smoother transitions than standard models, it is not suitable for applications requiring precise timing control, where electro-proportional valves would be more appropriate. The valve's response time varies from 150 ms to 300 ms depending on several factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is important to maintain positive pressure at port 1 to ensure consistent performance of the soft shift feature. Additionally, this model includes a push-type manual override control but is incompatible with weatherized coils when using this functionality. Constructed to be durable under high-pressure conditions up to 5000 psi (350 bar), the DMDASNN2E12V incorporates EPDM seals suitable for phosphate ester fluids while avoiding exposure to petroleum-based substances which can degrade the seals. The wet armature design of the solenoid means that heat generated by the coil directly affects the fluid surrounding it; this could lead to breakdowns in certain fluid types over extended periods. For environmental protection and operational reliability in various conditions, several coil connector options rated up to IP69K are available. The valve also features Sun\u2019s floating style construction which minimizes internal part misalignment caused by installation stresses or machining discrepancies. With a flow capacity of up to 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve is an effective solution for managing directional control in hydraulic circuits.

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.
