The Sun Hydraulics HDDAMCN212 (HDDAMCN212) is a versatile solenoid-after check cartridge valve designed for lift-lower applications, capable of being integrated directly into an actuator. This hybrid valve combines a direct acting solenoid poppet valve with a check function, allowing 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. Its robust design supports a fatigue rating of up to 5000 psi (350 bar), making it suitable for load holding applications. The valve features multiple manual override options, including configurations without manual override, although these are not compatible with weatherized coils. The wet armature design allows the working fluid to surround the armature, which may be affected by heat from long-term coil energization. This could impact fluids prone to breakdown at high temperatures, such as water-glycol mixtures. The Sun floating style construction minimizes internal part binding due to excessive installation torque or machining variations. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. The available coil connector options provide environmental protection ratings up to IP69K. The cartridge fits into a T11A cavity and offers a flow capacity of up to 10 gpm (40 L/min) with a typical response time of 50 ms. It has a maximum leakage rate of 10 drops/min at 110 SUS (24 cSt) under maximum operating pressure conditions. The HDDAMCN212 is engineered for reliability and longevity, offering mechanical life expectancy for its manual controls up to approximately 7,000 cycles and switching frequency capabilities of up to 15,000 cycles per hour. This makes it an ideal choice for applications requiring frequent actuation and precise control.
