The Sun Hydraulics DMDASPV812N (DMDASPV812N) is a solenoid-operated 3-way, 2-position cartridge valve designed for various hydraulic applications. This direct-acting, balanced spool directional valve features a soft shift option that moderates hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage from sudden pressure spikes. However, it's important to note that this feature increases response times (150 ms to 300 ms), which may not be suitable for applications requiring precise timing control. For such needs, Sun Hydraulics suggests considering their electro-proportional valves instead. The DMDASPV812N is engineered with a wet armature design where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods due to heat generation. The valve operates efficiently up to a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). It includes a push-type manual override control and incorporates Sun\u2019s floating style construction to minimize internal parts binding. This model uses EPDM seals compatible with phosphate ester fluids but vulnerable to petroleum-based fluids which can degrade the seals. Additionally, the solenoid's magnetic design ensures high efficiency and reliable valve shifting with minimal energy expenditure. The DMDASPV812N also offers various coil connector options rated up to IP69K for enhanced environmental protection against dust and moisture ingress. This makes it suitable for diverse industrial applications where robust performance and durability are critical.

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.
