The Sun Hydraulics DNDCXYN214N (DNDCXYN214N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient fluid control. This valve is spring-centered to the neutral position and allows for directional flow management based on coil activation. When coil A is energized, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. This product features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. Notably, it requires no minimum hydraulic pressure for operation due to its direct actuation design. The valve's wet armature design allows the working fluid to surround the armature, which can be advantageous in dissipating heat generated by the coil. However, users should be aware that certain fluids like water-glycol mixtures may degrade over time at these temperatures. The DNDCXYN214N incorporates Sun's floating style construction that helps prevent internal parts binding due to excessive installation torque or machining variations in the cavity. This model offers versatility with various coil termination and voltage options available, including weatherized coils for enhanced environmental protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also boasts a high-efficiency solenoid design that delivers substantial spool actuating force per watt expended. With a capacity of up to 5 gpm (20 L/min), this valve is suitable for differential flow circuits where higher return flows should be directed through specific ports. It has a typical response time of 50 ms and supports a switching frequency of up to 15,000 cycles per hour. The maximum valve leakage at standard conditions is minimal at just 10 in\u00b3/min (160 cc/min).
