The Sun Hydraulics HDDATCV298 (HDDATCV298) is a solenoid-operated check cartridge valve designed for demanding hydraulic applications. This hybrid valve integrates a direct-acting solenoid poppet valve with a 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. It is particularly suited for lift-lower and load-holding applications and can be directly integrated into actuators. The valve's solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability under high pressure. This model offers several manual override options, although these are not compatible with weatherized coils. The manual control assembly has an approximate mechanical life expectancy of 7,000 cycles, and the detent mechanism in the D or L control provides temporary actuation. Its wet armature design means the working fluid surrounds the armature, which can influence performance if the coil remains energized for extended periods, especially with water-glycol mixtures. The HDDATCV298 supports interchangeable coils with other Sun Series 1 solenoid products and features coil connector options rated up to IP69K for enhanced environmental protection. It incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations in cavity/cartridge interfaces. Additional specifications include a capacity of 10 gpm (40 L/min), a maximum operating pressure of 5000 psi (350 bar), and a typical response time of 50 ms. The valve's maximum leakage at 110 SUS (24 cSt) is limited to 10 drops/minute at 5000 psi (0.7 cc/min at 350 bar). The check cracking pressure is set at 30 psi (2 bar), and it can handle switching frequencies up to 15,000 cycles per hour.
