The Sun Hydraulics CNFBXAV (CNFBXAV) is a specialized hydraulic check valve designed to allow free flow from port 1 to port 2 while utilizing a customer-specified orifice to restrict flow in the opposite direction, from port 2 to port 1. This model is part of Sun Hydraulics' T3A cavity series and is distinguished by its use of a deeper relief style cavity, which means it is not interchangeable with Sun's standard check valves. The CNFBXAV can handle maximum operating pressures up to 5000 psi or 350 bar at both ports, accommodating a flow capacity of up to 30 gpm or approximately 120 L/min. The valve features an orifice range between .016 and .078 inches (0.4 to 2.0 mm), allowing for precise control tailored to specific application requirements. Notably, the specified orifice diameter is conveniently stamped on one of the hex faces of the cartridge for easy identification. Further enhancing its functionality, this model incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This valve also has specific installation parameters, with a required hex size of 1 1/8 inches (28.6 mm) and an installation torque between 45 and 50 lbf ft (61 - 68 Nm). The seal kit for this cartridge uses Viton components (part number: 990203006), ensuring robust performance and reliability in various hydraulic systems. This product is particularly suited for applications requiring reliable one-way flow control where custom flow restrictions are necessary, providing both versatility and precision in managing hydraulic flows.
