The Sun Hydraulics HDDAMCV712N (HDDAMCV712N) is a versatile solenoid-after check cartridge valve designed for applications requiring lift and lower functionality. It combines a direct-acting solenoid poppet valve with a check function, allowing 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. The valve is ideal for load-holding applications and can be integrated directly into an actuator. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. This cartridge offers multiple manual override options, although manual override functionality is not compatible with weatherized coils. The wet armature design allows the working fluid to surround the armature, which can influence performance if the coil remains energized for extended periods. Notably, some fluids like water-glycol mixtures may degrade at high temperatures over time, forming varnishes that could impact cartridge function. The HDDAMCV712N utilizes Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. It has a cavity size of T-11A and belongs to Series 1 with a capacity of handling up to 10 gpm (40 L/min). With a typical response time of 50 ms and minimal valve leakage at maximum operating pressure, it ensures efficient operation. Interchangeable with other Sun Series 1 solenoid products, its coil connector options provide ratings up to IP69K for enhanced environmental protection. Additional weatherized coils and kits are available for more comprehensive protection against harsh conditions. This robust design makes it suitable for various hydraulic systems requiring reliable control in demanding environments.
