The Sun Hydraulics HDDAMCN624N (HDDAMCN624N) is a versatile solenoid-operated check cartridge valve that integrates a direct-acting solenoid poppet valve subsequent to the check function. It facilitates 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. This hybrid valve is ideal for lift-lower applications and can be seamlessly integrated into an actuator. The solenoid tube assembly is engineered for durability, rated for service pressures up to 5000 psi (350 bar). It features various manual override options, including no manual override, with specific models offering temporary actuation via a detent mechanism in the manual override. The mechanical life expectancy of the D, L, and T control assemblies is approximately 7,000 cycles. The HDDAMCN624N is suitable for load-holding applications and employs a wet armature design where working fluid surrounds the armature. This design consideration is important as it exposes the fluid to heat generated by the coil during prolonged energization, potentially affecting certain fluids like water-glycol mixtures over time. The valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The cartridge uses Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It has a capacity of 10 gpm (40 L/min), a typical response time of 50 ms, and minimal leakage at maximum operating pressure. The check cracking pressure stands at 30 psi (2 bar), and it supports high switching frequencies up to 15,000 cycles per hour.
