The Sun Hydraulics DMDASNV712N (DMDASNV712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic flow control in various applications. This direct-acting, balanced spool directional valve features a unique soft shift capability that minimizes hydraulic shock during valve actuation, enhancing system longevity and performance stability. Although it offers smoother transitions compared to standard cartridges, it is not suitable for applications requiring critical timing control, where electroproportional valves might be more appropriate. The soft shift model significantly increases response times, typically ranging from 150 ms to 300 ms depending on factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is essential that port 1 maintains positive pressure to ensure consistent performance of the soft shift feature. Additionally, this model includes a push-type manual override control and incorporates Sun's floating style construction which helps prevent internal parts binding due to installation torque or cavity/cartridge machining variations. This valve is fatigue rated for service up to 5000 psi (350 bar) and has a maximum flow capacity of 5 gpm (20 L/min). It uses EPDM seals suitable for phosphate ester fluids but incompatible with petroleum-based fluids which can degrade the seals. The wet armature design of this valve means that the working fluid surrounds the armature; prolonged energization of the coil could lead to fluid degradation in certain conditions. For environments requiring robust protection against harsh conditions, additional weatherized coils and kits are available ensuring more comprehensive environmental resilience with connector options offering ratings up to IP69K. This specific model weighs approximately 0.60 lb (0.30 kg) and features a solenoid tube diameter of .75 inches (19 mm), making it a compact yet powerful component for advanced hydraulic systems.

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.
