The Sun Hydraulics DMDASBV712 (DMDASBV712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic systems. This direct-acting, balanced spool directional valve features a unique soft shift control that minimizes hydraulic shock during valve actuation, enhancing system longevity and stability. The soft shift functionality provides a slower response time ranging from 150 ms to 300 ms, dependent on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASBV712 is particularly suited for applications requiring gentle ramping of pressures where sudden changes could be detrimental to the system or the process. It is important to note that this valve should not be used in applications where precise timing control is crucial due to its increased response time compared to standard solenoids. For those requirements, Sun Hydraulics recommends considering their range of electro-proportional valves. This model includes a manual override feature with a push-type control mechanism; however, this feature is incompatible with weatherized coils. The valve's construction incorporates the Sun floating style design which reduces risks of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Rated for up to 5000 psi (350 bar) service and capable of handling flows up to 5 gpm (20 L/min), the DMDASBV712 ensures robust performance in demanding environments. The cartridge uses EPDM seals suitable for phosphate ester fluids but must avoid exposure to petroleum-based fluids which can degrade the seals. Additionally, the solenoid tube assembly of this model is fatigue rated at 5000 psi (350 bar), emphasizing its durability and suitability for high-pressure applications. With coil connector options providing protection up to IP69K and additional weatherized coils available for enhanced environmental resistance, the DMDASBV712 offers versatility and reliability in various hydraulic system configurations.

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.
