The Sun Hydraulics HDDAMCV612N (Material Number: HDDAMCV612N) is a sophisticated solenoid-after-check cartridge valve that combines a direct-acting solenoid poppet valve with a check function. This hybrid design facilitates flow from the inlet port 2 to system port 1, while blocking flow from port 2 to port 3 when the solenoid is de-energized. It is particularly useful in lift-lower applications and can be directly integrated into actuators. The solenoid tube assembly is designed to withstand fatigue at pressures up to 5000 psi (350 bar), ensuring durability in demanding environments. The valve features multiple manual override options, including configurations without manual override, although these are not compatible with weatherized coils. This cartridge utilizes a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil. This feature is crucial for prolonged coil energization periods as some fluids like water-glycol mixtures can degrade over time under high temperatures, potentially affecting cartridge performance. The valve\u2019s construction incorporates Sun's floating style design to reduce risks of internal part binding due to excessive installation torque or machining variations in cavity/cartridge. Additional features include interchangeable coils with other Sun Series 1 solenoid products and flexible mounting options for enhanced adaptability. Coil connectors support ratings up to IP69K for robust environmental protection, with further weatherized coils and kits available separately. The HDDAMCV612N offers a capacity of 10 gpm (40 L/min) and maintains maximum operating pressure at 5000 psi (350 bar). It exhibits a typical response time of 50 ms and a maximum leakage rate of 10 drops/minute at 110 SUS (24 cSt) viscosity under full pressure conditions.
