The Sun Hydraulics DMDASPV912 (DMDASPV912) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve is distinguished by its soft shift feature, which significantly reduces shock during valve actuation, enhancing system longevity and performance reliability. However, it is important to note that this feature may not be suitable for applications requiring critical timing or accurate ramping, where electroproportional valves might be more appropriate. The DMDASPV912 operates efficiently within a flow capacity of 5 gpm (20 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Its manual override feature includes a push-type control, although it is incompatible with weatherized coils. The valve also features EPDM seals specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model incorporates Sun's floating style construction to minimize internal part binding due to installation torque or cavity/cartridge machining variations. Additionally, the solenoid tube assembly of the DMDASPV912 is fatigue rated for high-pressure service up to 5000 psi (350 bar), ensuring durability and robust performance under demanding conditions. With a typical response time ranging between 150 ms to 300 ms \u2014 influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature \u2014 this valve is versatile but may not be ideal for high-speed applications. Overall, the Sun Hydraulics DMDASPV912 valve offers reliable operation with enhanced features like soft shifting and robust construction suited for various hydraulic systems needing controlled and gentle directional changes without the abrupt impacts typically associated with valve actuation.

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.
