The Sun Hydraulics DMDASNV814 (DMDASNV814) is a sophisticated solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation, enhancing system longevity and reducing noise. However, it is important to note that this soft shift feature may not be suitable for applications requiring precise timing control, as it increases the response time (150 ms to 300 ms) compared to standard solenoids. The valve is built to maintain consistent performance with port 1 under positive pressure and includes a push-type manual override control. It's important to consider that other manual control options are not compatible with the soft shift feature but can be implemented in the field if necessary. The design also incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), the DMDASNV814 is well-suited for a variety of demanding applications. Its solenoid tube assembly is fatigue rated for high-pressure service, ensuring reliability under strenuous conditions. Additionally, the valve's wet armature design means that the working fluid surrounds the armature; this aspect should be considered as some fluids may degrade at high temperatures. For environments requiring robust protection against elements, additional weatherized coils and kits are available, enhancing the durability of the valve system in harsh conditions. The coil connector options provide ratings up to IP69K, offering high levels of ingress protection. This product\u2019s versatility and advanced features make it an excellent choice for hydraulic systems requiring reliable directional control with optional soft shifting capabilities.

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.
