The Sun Hydraulics DNDCXAV224N (DNDCXAV224N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic flow management. This valve is spring-centered to a neutral position and features two operating states dependent on coil energization. When coil A is energized, hydraulic flow routes from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, coil B activation channels flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for fatigue resistance at pressures up to 5000 psi (350 bar), ensuring robust performance in demanding applications. Notably, this valve's direct actuation mechanism requires no minimum hydraulic pressure for operation, making it versatile across various system configurations. In differential flow circuits, optimal performance is achieved by directing higher return flows through specific ports as outlined in the product specifications. The valve incorporates EPDM seals suitable for phosphate ester fluid systems; however, exposure to petroleum-based substances can compromise seal integrity. The DNDCXAV224N's wet armature design allows the working fluid to surround the armature, absorbing heat generated during extended coil energization periods\u2014a crucial consideration in systems using water-glycol mixtures prone to breakdown under heat stress. The solenoid's magnetic design maximizes efficiency with high spool actuating force per watt expended. Moreover, coil interchangeability with other Sun Series 1 products enhances installation flexibility. This valve supports a variety of coil termination and voltage options with potential ratings up to IP69K for enhanced environmental protection. It also employs Sun's floating style construction technique to prevent internal part binding due to installation torque variations or machining discrepancies within the cavity/cartridge assembly. With a capacity of up to 5 gpm (20 L/min) and a typical response time of 50 ms, this valve is suitable for high-frequency switching applications up to 15,000 cycles per hour.
