The Sun Hydraulics HDDADCN828 (HDDADCN828) is a solenoid-after check cartridge valve designed for precise hydraulic control in lift-lower applications. This hybrid valve integrates a direct-acting solenoid poppet valve with a 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. The solenoid tube assembly is rated for up to 5000 psi (350 bar), making it suitable for load-holding applications and capable of being incorporated directly into actuators. This model offers several manual override options, including configurations without a manual override, and features a detent mechanism in the D or L control for temporary actuation. The mechanical life expectancy of the manual control assembly is approximately 7,000 cycles. It utilizes a wet armature design where working fluid surrounds the armature, which can influence performance if the coil remains energized for extended periods. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction, with connector options providing environmental protection ratings up to IP69K. The HDDADCN828 employs Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It fits into cavity T-11A, has a capacity of 10 gpm (40 L/min), and operates with a typical response time of 50 ms. The maximum valve leakage at standard conditions is minimal at 10 drops/min under full pressure. This cartridge's design includes features like switching frequency capabilities up to 15,000 cycles per hour and specific manual override force requirements. Additionally, it offers compatibility with Viton seal kits for enhanced durability and performance in demanding environments.
