The Sun Hydraulics DNDCXYE636 (DNDCXYE636) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control applications. This valve is spring-centered to the neutral position and offers versatile flow configurations depending on the coil that is energized. When coil A is activated, fluid flows 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 rated for fatigue at pressures up to 5000 psi (350 bar), making it suitable for demanding environments. A notable feature of this valve is its direct actuation, which eliminates the need for minimum hydraulic pressure during operation. It is particularly effective in differential flow circuits where higher return flows should be directed through specific ports as specified. The DNDCXYE636 utilizes a wet armature design that allows the working fluid to surround the armature, helping dissipate heat generated by the coil during prolonged energization periods. However, certain fluids like water-glycol mixtures may degrade over time due to this heat exposure. The valve offers a range of coil termination and voltage options with or without surge protection, allowing customization based on application needs. Its high-efficiency solenoid design ensures reliable shifting with minimal power consumption. Interchangeable coils compatible with Sun Series 1 solenoid products provide flexibility in installation and orientation. Additionally, it incorporates a floating style construction that minimizes internal binding risks due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min), typical response time of 50 ms, and maximum leakage specifications at defined viscosities and pressures, this valve is engineered for robust performance in various hydraulic systems.
