The Sun Hydraulics DNDCXBV224 (DNDCXBV224) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency fluid control. This valve features a spring-centered neutral position and operates with no minimum hydraulic pressure requirement. It is capable of managing flow from port 3 P to port 2 A and from port 4 B to port 1 T when coil A is energized, and from port 3 to port 4 and from port 2 to port 1 when coil B is energized. The solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring durability in demanding applications. This valve's wet armature design allows the working fluid to surround the armature, which can be beneficial for heat dissipation but may affect certain fluids like water-glycol mixtures over prolonged periods of energization. The DNDCXBV224 incorporates Sun\u2019s floating style construction, minimizing internal binding risks due to installation torque or cavity machining variations. A key feature of this model is its high-efficiency solenoid design that provides robust spool actuation force with minimal power expenditure, ensuring reliable operation. It offers interchangeable coils compatible with other Sun Series 1 solenoid products, supporting various termination and voltage configurations, including options for surge protection and environmental sealing up to IP69K. The valve's capacity reaches up to 5 gpm (20 L/min), with a typical response time of around 50 ms. It supports a switching frequency of up to 15,000 cycles per hour and maintains maximum leakage rates at specified conditions. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended; however, these should not be exposed to petroleum-based substances. This versatile spool valve serves as a crucial component in differential flow circuits where higher return flows are managed efficiently through specific ports.
