The Sun Hydraulics DNDCXCV948 (DNDCXCV948) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic control. This valve is spring-centered to the neutral position and offers precise flow direction when either coil A or B is energized. Specifically, energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is rated for high-pressure applications up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. This valve requires no minimum hydraulic pressure for operation, making it suitable for various applications without the need for additional pressure sources. It features a wet armature design where the working fluid surrounds the armature, which may affect performance if exposed to prolonged heat generated by the coil. The DNDCXCV948 includes EPDM seals compatible with phosphate ester fluids but should avoid petroleum-based substances due to potential seal damage. The valve's high-efficiency solenoid design delivers strong spool actuating force per watt expended, ensuring reliable shifting even under challenging conditions. It incorporates Sun Hydraulics' floating style construction to reduce internal binding risks caused by excessive installation torque or machining variations. The DNDCXCV948 supports a wide range of coil termination and voltage options, with interchangeable coils compatible with other Sun Series 1 products. Additionally, it offers robust environmental protection with available weatherized coils rated up to IP69K. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 ms, this valve provides efficient fluid control in hydraulic systems requiring rapid switching frequencies of up to 15,000 cycles per hour. The DNDCXCV948 also includes Viton seal kits for both cartridge and coil components.
