The Sun Hydraulics HDDALCN224N (HDDALCN224N) is a solenoid-after-check cartridge hybrid valve designed for applications that require reliable lift and lower functions. This advanced cartridge valve integrates a direct-acting solenoid poppet valve in conjunction with a check valve, 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. With its robust design, it is particularly suitable for load-holding applications and can be seamlessly integrated into actuators. The solenoid tube assembly is engineered to withstand up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This model offers several manual override options, although manual overrides are not compatible with weatherized coils. It features a wet armature design, which means that the working fluid surrounds the armature and can be affected by coil heat if energized for extended periods. Therefore, certain fluids like water-glycol mixtures may degrade over time due to heat exposure, potentially affecting performance. The valve's construction incorporates Sun's floating style technology to reduce the risk of internal component binding due to excessive installation torque or machining variations. It has a capacity of 10 gpm (40 L/min) and responds within approximately 50 ms under typical conditions. The HDDALCN224N also boasts interchangeable coils with other Sun Series 1 solenoid products and provides coil connector options rated up to IP69K for enhanced environmental protection. With a mechanical life expectancy of around 7,000 cycles for models equipped with D or L control detent mechanisms and a switching frequency capability of up to 15,000 cycles per hour, this versatile cartridge is well-suited for demanding hydraulic systems requiring efficient directional control and pressure management.
