The Sun Hydraulics CXFCXZN (CXFCXZN) is a specialized hydraulic check valve designed for high-performance and reliability in fluid power applications. This model features a unique free-flow, nose-to-side cheater check valve function, which operates as a standard 2-port check valve when the third port of the cartridge is blocked. This makes it particularly useful in circuits that require a check valve in an existing three-port cavity. Engineered to handle up to 40 gallons per minute (160 L/min) with a maximum operating pressure of 5000 psi (350 bar), it ensures robust operation under demanding conditions. The CXFCXZN is distinguished by its extremely low leakage rate, with less than one drop per minute (0.07 cc/min), ensuring efficient system performance with minimal fluid loss. The construction incorporates Sun\u2019s floating style design which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This feature enhances the longevity and reliability of the valve under various operational conditions. For installation, the valve requires a hex size of 1 1/8 inches (28.6 mm) and an installation torque between 45 - 50 lbf ft (61 - 68 Nm). The use of Viton seals (part number: 990202006) further contributes to its durability and suitability for high-pressure environments. With these specifications, the Sun Hydraulics CXFCXZN offers an optimal solution for hydraulic systems requiring precise fluid control with minimal maintenance and downtime.
