The Sun Hydraulics HDDATCV812 (HDDATCV812) is a solenoid-after check cartridge valve designed for versatile hydraulic applications, particularly in lift-lower operations. This hybrid valve integrates a direct-acting solenoid poppet valve with a check function, facilitating flow from the inlet port 2 to the system port 1 while blocking flow from port 2 to port 3 when the solenoid is de-energized. The HDDATCV812 is suitable for load-holding applications and can be directly integrated into an actuator. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve offers several manual override options, including configurations without manual override, although these are not compatible with weatherized coils. Its wet armature design allows working fluid to surround the armature, which can be influenced by heat generated during prolonged coil energization\u2014important to consider when using fluids like water-glycol mixtures that may degrade over time. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction while offering connector options rated up to IP69K for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal part binding due to excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), this cartridge valve is designed for efficient operation with typical response times of around 50 ms and minimal leakage rates. It comes equipped with various seal kits, such as Viton: 990011006 for the cartridge and Viton: 990770006 for the coil, ensuring reliable sealing performance under diverse conditions.
