The Sun Hydraulics DMDASAN71219 (DMDASAN71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring reliable directional control. This direct-acting, balanced spool valve features a soft shift option that moderates the shock typically associated with valve actuation. While enhancing system smoothness, this soft shift feature slightly increases the response time, which ranges from 150 ms to 300 ms depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASAN71219 is engineered to deliver consistent performance when port 1 is under positive pressure. It includes a push-type manual override control which provides an additional layer of operational flexibility; however, it's important to note that other manual control options are not compatible with the soft shift feature but can be added in the field if necessary. The construction of this valve incorporates Sun\u2019s floating style design to minimize internal parts binding and ensure smooth operation even under varying installation conditions. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), the DMDASAN71219 is capable of handling robust applications. It also features an innovative magnetic design in its solenoid that maximizes efficiency and spool actuating force per watt expended. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long-term performance. Additionally, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it can damage these seals. Overall, the Sun Hydraulics DMDASAN71219 offers advanced hydraulic control with enhanced soft shifting capabilities suitable for various applications where smooth operation is crucial.

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.
