The Sun Hydraulics HDDATCN548 (HDDATCN548) is a solenoid-after-check cartridge valve designed for applications requiring precise control and reliability, such as lift-lower operations. This hybrid valve combines a direct-acting solenoid poppet 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. The valve's construction supports integration directly into actuators, making it suitable for load-holding applications. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This model offers various manual override options, including configurations without an override, though it should be noted that manual overrides are incompatible with weatherized coils. The HDDATCN548 features a wet armature design where the working fluid surrounds the armature, potentially impacting performance if the coil remains energized for extended periods due to heat exposure. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connectors offer ratings up to IP69K for enhanced environmental protection, with additional weatherized coils and kits available. The valve incorporates Sun's floating style construction to minimize binding risks from excessive installation torque or machining variations. It operates within a cavity T-11A and has a capacity of 10 gpm (40 L/min). With a typical response time of 50 ms and a maximum leakage rate of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar), this cartridge ensures efficient performance in demanding scenarios. Its switching frequency is rated at up to 15,000 cycles per hour, supporting high-frequency operations with reliable performance over its mechanical life expectancy of approximately 7,000 cycles for models equipped with D or L control detent mechanisms.
