The Sun Hydraulics HDDADCV912N (HDDADCV912N) is a versatile solenoid-after check cartridge valve designed for lift-lower applications and can be seamlessly integrated into actuators. This hybrid valve features a direct-acting solenoid poppet valve connected after the check function, allowing flow from inlet port 2 to system port 1 while blocking flow from port 2 to port 3 when the solenoid is de-energized. It is particularly suitable for load-holding applications and utilizes a wet armature design, where the working fluid surrounds the armature, exposing it to coil-generated heat. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade under prolonged heat exposure. The valve's robust construction includes a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability in demanding conditions. It offers several manual override choices, although manual override functionality is incompatible with weatherized coils. The manual control assembly has an estimated mechanical life expectancy of approximately 7,000 cycles and requires a force of 5 lbs/1000 psi at Port 1 for actuation. With interchangeable coils compatible with other Sun Series 1 solenoid products, installation flexibility is enhanced as coils can be mounted in either direction on the tube. Coil connector options provide ratings up to IP69K for superior environmental protection, and additional weatherized coils and kits are available for enhanced durability in harsh conditions. The valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations, ensuring reliable performance. With a capacity of up to 10 gpm (40 L/min) and a response time of about 50 ms, this cartridge offers efficient operation across various settings.
