The Sun Hydraulics DNCATCV223 (DNCATCV223) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. It features a closed transition between positions, which minimizes oil loss during shifting\u2014an essential characteristic for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible, it is not recommended due to potential performance issues. Engineered for durability, the solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. This valve does not require a minimum hydraulic pressure to function and utilizes a wet armature design that allows the working fluid to cool the coil, though caution is advised with certain fluids like water-glycol mixtures that may degrade at high temperatures. The DNCATCV223 offers flexibility with various coil termination and voltage options available, including configurations with surge protection. The solenoid's magnetic design provides high efficiency, delivering significant spool actuating force per watt expended for dependable valve shifting. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either orientation. For enhanced environmental protection, coil connector options are rated up to IP69K, with additional weatherized coils and kits available. This valve incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 8 gpm (30 L/min) and a response time of approximately 50 ms, it supports switching frequencies up to 15,000 cycles per hour. The manual override requires minimal force and provides precise control when necessary. The DNCATCV223 weighs approximately .60 lb (.30 kg) and has specific installation requirements detailed in its technical specifications.
