The Sun Hydraulics HDDADCV223 (HDDADCV223) is a solenoid-after check cartridge valve that combines a direct acting solenoid poppet valve with a check function. This hybrid valve 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. It is primarily used in lift-lower applications and can be integrated directly into actuators, making it suitable for load holding tasks. The solenoid tube assembly is designed to withstand pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding conditions. The manual override mechanism, available in several configurations including options without manual override, has a mechanical life expectancy of approximately 7,000 cycles, although it is not compatible with weatherized coils. This valve employs a wet armature design where the working fluid surrounds the armature, which can impact performance if the coil remains energized for extended periods, particularly with fluids like water-glycol mixtures that may degrade at high temperatures. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube, offering flexibility during installation. Additionally, connector options provide protection ratings up to IP69K for enhanced environmental resilience. Key specifications include a cavity size of T-11A, series designation of 1, and a capacity of 10 gpm (40 L/min). It features a response time of approximately 50 ms and demonstrates minimal leakage at maximum operating pressure\u201410 drops/min at 5000 psi (0.7 cc/min at 350 bar). The check cracking pressure is set at 30 psi (2 bar), and it supports switching frequencies up to 15,000 cycles per hour. The valve's robust construction minimizes internal part binding due to excessive installation torque or machining variations.
