The Sun Hydraulics DMDASAN712N (DMDASAN712N) 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 minimizes shock during valve actuation, although it is not suitable for applications where precise timing control is critical. For such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The soft shift model has an increased response time compared to the standard solenoid, with typical response times ranging from 150 ms to 300 ms depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It requires port 1 to be at positive pressure for consistent performance and includes a push-type manual override control. Note that other manual control options are not compatible with the soft shift feature but can be installed in the field if necessary. This model is constructed with EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids will damage these seals. The valve also features a wet armature design where the working fluid surrounds the armature which could lead to fluid breakdown if the coil remains energized for extended periods. Designed for durability and efficient performance, the DMDASAN712N has a fatigue rating of 5000 psi (350 bar). It incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The solenoid\u2019s magnetic design ensures high efficiency and reliable valve shifting. This model is ideal for applications requiring moderate flow control and shock reduction in hydraulic systems. It supports environmental protection options with additional weatherized coils and kits available separately for enhanced durability against harsh conditions.

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.
