The Sun Hydraulics DMDASAN812N (DMDASAN812N) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic control applications. This direct-acting, balanced spool directional valve features a soft shift option that moderates the impact of valve actuation, thereby reducing system shock. This capability is particularly beneficial in applications sensitive to sudden changes in pressure or flow but is not recommended for scenarios where precise timing control is critical. For those requirements, electro-proportional valves might be better suited. The soft shift model differentiates itself by having a slower response time compared to standard solenoid cartridges offered by Sun Hydraulics, with typical response times varying from 150 ms to 300 ms depending on several factors including flow, pressure, coil voltage, oil viscosity, and ambient temperature. The performance of the soft shift feature is optimized when port 1 maintains positive pressure. This model includes a push-type manual override and boasts a solenoid tube assembly rated for fatigue at 5000 psi (350 bar). It's important to note that cartridges fitted with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based fluids can damage the seals. The design incorporates a wet armature setup where the working fluid surrounds the armature which may affect fluid integrity under prolonged energization. Additionally, this valve uses Sun\u2019s floating style construction which minimizes internal binding risks due to installation torque or cavity/cartridge machining variations. The solenoid\u2019s design ensures high efficiency and effective spool actuation force per Watt expended for reliable operation. Various coil connector options are available with ratings up to IP69K for enhanced environmental protection against elements like dust and water ingress.

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.
