The Sun Hydraulics DMDASAN812 (DMDASAN812) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic system applications requiring reliable directional control. This direct-acting, balanced spool valve is distinguished by its soft shift feature, which moderates hydraulic shock during valve actuation, thereby enhancing system longevity and reducing noise. However, it is important to note that the soft shift design may result in slower response times (ranging from 150 ms to 300 ms), making it less suitable for applications where precise timing control is critical. For such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASAN812 model incorporates a manual override with a push-type control and is compatible with various manual override options available for field installation. It features a robust solenoid tube assembly rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve\u2019s construction includes EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Additionally, this model employs 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 exposure. The unique magnetic design of the solenoid ensures high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. With a flow capacity of up to 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), the DMDASAN812 is well-suited for various hydraulic applications requiring efficient flow control and directional management. Its design minimizes internal part binding thanks to Sun's floating style construction, accommodating slight variations in installation torque and cavity/cartridge machining.

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.
