The Sun Hydraulics DMDASBN212N (DMDASBN212N) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring directional control. This direct-acting, balanced spool valve is characterized by its soft shift feature, which moderates shock from valve actuation, making it suitable for systems where the reduction of mechanical shock is preferred, though it should not be used in applications where precise timing control is critical. The soft shift model has a slower response time ranging from 150 ms to 300 ms compared to standard solenoids. The DMDASBN212N incorporates a manual override with a push-type control option and boasts a robust solenoid tube assembly rated for up to 5000 psi (350 bar). The valve operates optimally when port 1 maintains positive pressure. It features EPDM seals intended specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, the wet armature design of the valve means that the working fluid surrounds the armature which might be susceptible to heat during prolonged energization. For environmental protection and reliability in various operating conditions, this model offers coil connector options with ratings up to IP69K and additional weatherized coils. Its design minimizes internal parts binding through Sun\u2019s floating style construction technique. The maximum operating capacity of this model is 5 gpm (20 L/min) with a maximum leakage at 3000 psi being relatively low at 5 in\u00b3/min. This versatile cartridge valve is an efficient solution particularly for mobile and industrial applications requiring reliable performance under varying environmental conditions and where gentle shifting is beneficial to the system\u2019s operation.

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.
