The Sun Hydraulics DMDASPN212 (DMDASPN212) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to manage the flow and direction of hydraulic fluid within a system efficiently. Its soft shift feature moderates the shock typically associated with valve actuation, enhancing system stability and reducing potential damage from hydraulic spikes, although it isn't suitable for applications requiring precise timing control. The valve boasts a response time between 150 ms to 300 ms, varying with factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, it is essential that port 1 maintains positive pressure. The manual override functionality included in this model provides additional control flexibility but is not compatible with weatherized coils. Constructed for durability under high pressures up to 5000 psi (350 bar), the solenoid tube assembly of this valve is fatigue rated for demanding applications. The use of EPDM seals specifies its compatibility with phosphate ester fluids while cautioning against exposure to petroleum-based substances which could degrade the seals. Additionally, its wet armature design means that prolonged energization of the coil should be managed carefully to avoid degradation of certain hydraulic fluids. This model also features a unique magnetic design in the solenoid which enhances efficiency and reliability in valve shifting. Various coil connector options are available up to an IP69K rating for superior environmental protection against dust and moisture ingress. With its floating style construction, the DMDASPN212 minimizes internal part binding due to installation variances or machining discrepancies in cartridge cavities. Overall dimensions include a solenoid tube diameter of 0.75 inches (19 mm) and a hex size for the valve at 7/8 inches (22.2 mm). The installation torque requirement ranges from 30-35 lbf\u00b7ft (41-47 Nm), ensuring secure fitting without excessive force application. This robust yet sophisticated component weighs approximately 0.60 lb (0.30 kg), integrating seamlessly into various hydraulic systems where moderate flow control and directional management are needed.

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.
