The Sun Hydraulics HDDADCN72419 (HDDADCN72419) is a solenoid-after check cartridge hybrid valve designed for precise control in hydraulic systems. This innovative valve combines a direct-acting solenoid poppet valve with a check valve function, allowing for controlled fluid 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. It is particularly suited for lift-lower applications and can be integrated directly into an actuator, making it ideal for load holding scenarios. The solenoid tube assembly is robust, fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring reliable performance under demanding conditions. The HDDADCN72419 features several manual override options, including models with detent mechanisms designed for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. It utilizes a wet armature design where working fluid surrounds the armature and is exposed to heat generated by the coil. This design consideration is important as some fluids may degrade over time at elevated temperatures, potentially affecting cartridge function. The valve\u2019s coils are interchangeable with other Sun Series 1 solenoid products and offer various connector options rated up to IP69K for enhanced environmental protection. Additional specifications include a cavity size of T-11A, Series 1 capacity of 10 gpm (40 L/min), and maximum leakage at 110 SUS (24 cSt) limited to 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The valve also features Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. Suitable seal kits are available in Viton material, ensuring compatibility and durability in various operational environments.
