The Sun Hydraulics DMDASPV712 (DMDASPV712) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency hydraulic system control. This direct-acting, balanced spool directional valve features a unique soft shift capability that minimizes hydraulic shock during valve actuation, making it suitable for applications sensitive to sudden changes in pressure or flow. Although the soft shift model offers reduced performance limits compared to the standard cartridge, it significantly increases response times ranging from 150 ms to 300 ms depending on various factors such as flow rate and oil viscosity. The DMDASPV712 operates optimally when port 1 is under positive pressure and incorporates a push-type manual override for additional control flexibility. Notably, this manual override feature is incompatible with weatherized coils. The valve is designed with a wet armature setup where the working fluid surrounds the armature\u2014this aspect should be considered in applications where the coil remains energized for extended periods. With a maximum operating capacity of 5 gpm/20 L/min and pressure up to 5000 psi/350 bar, this valve is robust enough for demanding operations. It also features environmental protection options like IP69K-rated coil connectors and additional weatherized coils for enhanced durability against harsh conditions. The construction of the DMDASPV712 employs Sun's floating style design which helps prevent internal parts binding due to installation stresses or cavity/cartridge machining inconsistencies. This model also boasts high spool actuating force per watt expended due to its efficient magnetic design, ensuring reliable valve shifting even under challenging operational circumstances.

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.
