The Sun Hydraulics HDDAMCN214N (HDDAMCN214N) is a versatile solenoid-after check cartridge valve designed for lift-lower and load-holding applications. This hybrid valve integrates a direct-acting solenoid poppet valve that tees in after the check function, allowing flow from inlet port 2 to system port 1 while blocking flow from port 2 to port 3 when the solenoid is de-energized. The valve is suitable for integration directly into actuators, offering reliable performance with a fatigue rating of up to 5000 psi (350 bar). It features a wet armature design, which means the working fluid surrounds the armature, potentially impacting performance with certain fluids like water-glycol mixtures if energized for extended periods. The HDDAMCN214N offers multiple manual override options, including models without manual override. However, manual override is not compatible with weatherized coils. The D or L control models include a detent mechanism intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The interchangeable coil design allows compatibility with other Sun Series 1 solenoid products and can be mounted in either direction. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. This cartridge utilizes Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min), it operates effectively within its specified parameters and maintains minimal leakage rates at maximum operating pressure. The valve's switching frequency reaches up to 15,000 cycles per hour, ensuring quick response times typical at around 50 ms. Installation requires careful attention to torque specifications and seal kit compatibility for optimal performance and longevity.
