The Sun Hydraulics CNCDXFN (CNCDXFN) is a specialized hydraulic valve designed for precise fluid control in various hydraulic systems. This model is a free flow, side-to-nose cheater check valve featuring a bypass orifice, which functions as a 2-port check valve within a 3-port cavity. It efficiently allows free flow from port 2 to port 1, while the flow from port 1 to port 2 is controlled by an orifice whose diameter can be specified by the customer and is marked on one of the cartridge's hex faces. The CNCDXFN valve is particularly useful in full-time regeneration circuits, enabling full force development by a cylinder upon stopping. The bypass orifice effectively drops rod end pressure to zero when the flow out of the rod ceases, ensuring efficient operation and energy conservation in hydraulic systems. Its construction incorporates Sun's floating style design which minimizes internal part binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. Key specifications of the CNCDXFN include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 15 gpm (60 L/min), and an adjustable orifice range from .016 to .153 inches (0.4 to 3.9 mm). The valve's hex size is 7/8 inches (22.2 mm), and it requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). The model weighs approximately .30 lb (0.15 kg) and utilizes Viton seals for enhanced durability and performance under various operational conditions. This model's adaptability and robust construction make it ideal for high-pressure applications requiring precise fluid control and reliability.
