The Sun Hydraulics DNDCXWEHN24AB (DNDCXWEHN24AB) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient fluid control in hydraulic systems. This valve is spring-centered to the neutral position and offers versatile flow paths depending on the coil activation. When coil A is energized, flow occurs from port 3 P to port 2 A and from port 4 B to port 1 T; when coil B is energized, flow shifts from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly supports fatigue-rated service up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. This valve operates without requiring a minimum hydraulic pressure, making it suitable for differential flow circuits where higher return flow should pass through port 2 A to port 1 T. It features EPDM seals compatible with phosphate ester fluids but cautions against exposure to petroleum-based fluids. The wet armature design allows the working fluid to surround the armature, which can affect performance if the coil remains energized for extended periods due to potential fluid breakdown at high temperatures. The DNDCXWEHN24AB includes a high-efficiency solenoid with significant actuating force per watt, contributing to reliable valve switching. Coils are interchangeable with other Sun Series 1 products and offer various termination and voltage options with potential surge protection. Coil connectors can achieve ratings up to IP69K for enhanced environmental resilience. The valve's floating style construction minimizes risks of internal binding due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min) and rapid response time of approximately 50 ms, this valve supports a maximum operating pressure of up to 5000 psi (350 bar). Its robust design makes it suitable for applications requiring frequent switching cycles\u2014up to 15,000 cycles per hour\u2014while maintaining minimal leakage rates under specified conditions.
