The Sun Hydraulics DNDCXYV736 (DNDCXYV736) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise fluid control in hydraulic systems. This valve is spring-centered to the neutral position and operates by energizing either coil A or coil B. When coil A is activated, it directs flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The DNDCXYV736 does not require minimum hydraulic pressure for operation, making it highly versatile in various applications. It features a wet armature design where the working fluid surrounds the armature, which can influence performance if the coil is energized for extended periods. The valve is compatible with EPDM seals for systems using phosphate ester fluids but should avoid petroleum-based fluids as they can damage the seals. This model offers a high-efficiency solenoid design that provides significant spool actuating force per watt expended, enhancing reliability in valve shifting operations. It supports a variety of coil termination and voltage options, including configurations with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The DNDCXYV736 incorporates Sun's floating style construction to reduce potential binding issues due to installation torque or machining variations. With a capacity of 5 gpm (20 L/min) and a response time of approximately 50 ms, this valve ensures efficient operation with minimal leakage at maximum pressures. It also supports high switching frequencies up to 15,000 cycles per hour and features robust environmental protection options through weatherized coils and kits available separately.
