The Sun Hydraulics DNCATBV224 (DNCATBV224) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional design. This valve features a closed transition between positions, significantly reducing oil loss during shifting, which is particularly beneficial for pilot control circuits. It is designed with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring robust service in demanding applications. Notably, the valve operates without needing a minimum hydraulic pressure and uses EPDM seals suitable for systems with phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. The valve's wet armature design allows the working fluid to cool the coil but requires consideration of fluid breakdown at high temperatures over prolonged energization periods. The DNCATBV224 offers various coil termination and voltage options, including those with surge protection, contributing to its versatility in different setups. Its high-efficiency solenoid design provides substantial spool actuating force per watt expended, enhancing reliability in valve shifting operations. The interchangeable coils can be mounted in either direction on the tube and offer IP69K-rated connector options for superior environmental protection. Additionally, this model incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. With a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve exhibits rapid response times of approximately 50 ms and can handle switching frequencies up to 15,000 cycles per hour. It also features manual override capabilities with specific force requirements and stroke dimensions for user convenience.
