The Sun Hydraulics CXJCXZN (CXJCXZN) is a versatile hydraulic check valve designed for high-efficiency applications requiring minimal fluid leakage. This model operates as a standard 2-port check valve within a 3-port cavity, with the third port blocked off, making it ideal for circuits that originally contain three-port cavities but only require a check valve function. The CXJCXZN stands out due to its extremely low leakage rate, which is less than one drop per minute or 0.07 cc/min, ensuring almost no fluid loss and maintaining system integrity. This valve incorporates Sun\u2019s floating style construction, which significantly reduces the risk of internal parts binding\u2014a common issue in systems where excessive installation torque or variations in cavity/cartridge machining might occur. It is specifically designed to fit the T19A cavity and belongs to Sun\u2019s Series 4 line of products. The CXJCXZN can handle a substantial flow capacity of up to 120 gpm (480 L/min) and withstands a maximum operating pressure of 5000 psi (350 bar). For installation, this model requires a valve hex size of 1-5/8 inches (41.3 mm) and an installation torque between 350 - 375 lbf\u00b7ft (474 - 508 Nm). The seal kit for this cartridge uses Viton material, designated by part number: 990019006. These specifications ensure that the CXJCXZN check valve is robust, reliable, and capable of meeting rigorous industrial demands while providing ease of maintenance and long service life.
