The Sun Hydraulics HDDALCN924 (HDDALCN924) is a solenoid-after check cartridge valve designed for hybrid applications, combining a direct-acting solenoid poppet valve with a check function. The valve facilitates flow from inlet port 2 to system port 1, while blocking flow from port 2 to port 3 when the solenoid is de-energized. This configuration makes it ideal for lift-lower applications and direct integration into actuators. The valve's solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. Equipped with various manual override options, including no manual override, the HDDALCN924 offers temporary actuation via its D, L, and T control mechanisms, which have a mechanical life expectancy of around 7,000 cycles. However, it should be noted that manual override functionality is incompatible with weatherized coils. The valve utilizes a wet armature design that allows working fluid to surround the armature and absorb heat generated by the coil. Users should consider this factor when using fluids like water-glycol mixtures that may degrade over time at elevated temperatures. The HDDALCN924 supports load-holding applications and incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. It features interchangeable coils compatible with other Sun Series 1 solenoid products and offers coil connector options rated up to IP69K for enhanced environmental protection. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this cartridge valve exhibits maximum leakage of just 10 drops/min at 110 SUS (24 cSt). The valve's compact design includes a cavity size of T-11A and a hex size of .78 inches (22.2 mm), making it versatile for various hydraulic applications.
