The Sun Hydraulics DMDASAV71219 (DMDASAV71219) 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 valve features a soft shift option that significantly diminishes shock during valve actuation, enhancing system longevity and reducing wear. However, it's important to note that the soft shift feature increases the response time, typically ranging from 150 ms to 300 ms, which might not be suitable for applications requiring critical timing or rapid actuation. The DMDASAV71219 includes a manual override feature with a push-type control. It offers flexibility in manual adjustments while ensuring compatibility with field installations of other manual controls. The solenoid tube assembly of this model is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance even under high-pressure conditions. The valve is equipped with EPDM seals designed specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This model also utilizes a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil can lead to higher fluid temperatures affecting fluid properties and potentially impacting performance. The innovative magnetic design of the solenoid ensures high efficiency and effective spool actuating force per watt expended, resulting in reliable valve shifting. Additionally, the DMDASAV71219 benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With options for weatherized coils and IP69K rated coil connectors available, this valve is adaptable for harsh environments ensuring consistent performance and durability across various 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.
