The Sun Hydraulics DNDCXHV836 (DNDCXHV836) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic flow control. This valve is spring-centered to the neutral position and allows fluid flow from port 3 P to port 2 A and from port 4 B to port 1 T when coil A is energized. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for high durability, with a fatigue rating of up to 5000 psi (350 bar). It operates without the need for minimum hydraulic pressure, making it versatile in various applications. The valve is particularly suitable for differential flow circuits where higher return flows should be routed through ports A and T. It features EPDM seals compatible with phosphate ester fluids but cautions against exposure to petroleum-based substances due to potential damage. The wet armature design ensures that the working fluid surrounds the armature, which can be affected by prolonged coil energization due to heat generation. This model offers a range of coil termination and voltage options, including those with surge protection, providing adaptability in different configurations. The high-efficiency solenoid design results in significant spool actuating force per watt used, ensuring reliable operation. Coils are interchangeable with other Sun Series 1 products and can be mounted bidirectionally on the tube. Connector options provide ratings up to IP69K for enhanced environmental protection. The floating style construction minimizes internal binding risks caused by installation torque or machining variations. With a capacity of 5 gpm (20 L/min), a typical response time of 50 ms, and maximum leakage at specific conditions of up to 10 in\u00b3/min (160 cc/min), this valve demonstrates robust performance characteristics suitable for demanding hydraulic systems.
