The Sun Hydraulics DMDASRV712 (DMDASRV712) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically crafted to offer soft shift capabilities, which help in minimizing hydraulic shock during valve actuation. Although it enhances the smoothness of operation, the soft shift feature results in longer response times ranging from 150 ms to 300 ms and should not be relied upon for applications requiring precise timing control. This model is engineered with a push-type manual override control and boasts a robust solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar) service. The cartridge\u2019s wet armature design allows the working fluid to surround the armature, which can be critical when considering the type of fluid used due to potential breakdowns at high temperatures. Additionally, this valve supports environmental adaptability with coil connector options that can achieve ratings up to IP69K for heightened protection against dust and water ingress. It also features Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or cavity/cartridge machining variations. The DMDASRV712 is suitable for use in systems with phosphate ester fluids when configured with EPDM seals; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. With a capacity of up to 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve is designed for efficient performance across various hydraulic applications while ensuring reliability through its innovative construction and design features.

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.
