The Sun Hydraulics DNDCXCV (DNDCXCV) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency and reliable performance in hydraulic systems. This valve is spring-centered to the neutral position and functions by directing flow between ports based on the energized coil. When coil A is activated, flow transitions 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. The valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under demanding conditions. Notably, this valve does not require a minimum hydraulic pressure for operation due to its direct actuation design. It features a wet armature design which allows the working fluid to surround the armature, providing exposure to heat generated by the coil\u2014a consideration for long-term energization scenarios as some fluids may degrade over time at elevated temperatures. The DNDCXCV incorporates Sun's floating style construction, minimizing risks of internal binding due to installation torque or machining variations. This model offers a variety of coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. These can be mounted bi-directionally on the tube and include weatherized options for enhanced environmental protection, with some connector options rated up to IP69K. Its high-efficiency solenoid design ensures robust spool actuating force per watt expended for dependable valve shifting. Additionally, it supports differential flow circuits by directing higher return flows through specific ports as needed. The valve fits into cavity T31A with a capacity of up to 5 gpm (20 L/min) and features a typical response time of approximately 50 ms. It accommodates various seal kits, including those made from Viton material for specific fluid compatibility requirements.
