The Sun Hydraulics DNDCXCV236 (DNDCXCV236) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic flow control. This valve is spring-centered to the neutral position and offers versatile flow direction depending on coil activation. When coil A is energized, hydraulic fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is fatigue-rated for high-pressure applications up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. This model does not require a minimum hydraulic pressure for operation due to its direct actuation design. It features a wet armature design where the working fluid surrounds the armature, which may influence performance if the coil remains energized for extended periods. Careful consideration is needed when using fluids like water-glycol mixtures that can degrade at high temperatures. The DNDCXCV236 provides a high-efficiency solenoid with significant spool actuating force per watt expended, promoting reliable valve shifting. It incorporates Sun's floating style construction, minimizing internal binding risks due to excessive installation torque or machining variations. The valve supports various coil termination and voltage options, including surge protection capabilities. For optimal performance, cartridges with EPDM seals should be used with phosphate ester fluids only; exposure to petroleum-based substances can cause seal damage. The valve accommodates differential flow circuits by directing higher return flows through specific ports as needed. With a capacity of 5 gpm (20 L/min) and a typical response time of just 50 milliseconds, this robust component suits applications requiring rapid switching frequencies up to 15,000 cycles per hour.
