The Sun Hydraulics DNCADAN72499 (DNCADAN72499) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve ensures a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a critical feature in pilot control circuits. It operates efficiently with a capacity based on port 3 as the inlet and port 1 as the tank, although it allows reverse flow under certain conditions. With a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), this valve guarantees reliable performance even under strenuous service conditions. It requires no minimum hydraulic pressure for operation, making it versatile across different hydraulic systems. The DNCADAN72499 is equipped with EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage by petroleum-based fluids. This model incorporates a wet armature design where the working fluid surrounds the armature. Although beneficial for certain applications, prolonged energization of the coil can lead to fluid degradation at high temperatures. The valve offers a variety of coil termination and voltage options to suit diverse operational needs and environments, including options with IP69K ratings for enhanced protection against harsh conditions. Sun Hydraulics has designed this valve with interchangeable coils compatible with other Series 1 solenoid products and features a unique magnetic design that enhances efficiency and spool actuating force per Watt expended. Furthermore, its floating style construction minimizes internal part binding due to installation variations or cavity/cartridge machining errors. With specifications like an 8 gpm (30 L/min) capacity, maximum operating pressure of 5000 psi (350 bar), and fast response times typically around 50 ms, the DNCADAN72499 is engineered to meet rigorous industrial demands while maintaining high reliability and performance.
