The Sun Hydraulics CXFCXEN (CXFCXEN) is a free-flow, nose-to-side cheater check valve designed for specialized hydraulic applications. This valve operates as a standard 2-port check valve when the third port of its 3-port cavity is blocked, making it particularly useful in scenarios where a check valve is needed in an existing three-port setup. With a capacity to handle flow rates up to 40 gpm (160 L/min) and a maximum operating pressure of 5000 psi (350 bar), the CXFCXEN is built to manage demanding conditions. This model features extremely low leakage rates, with a maximum leakage restricted to less than one drop per minute (0.07 cc/min), ensuring efficient and reliable operation in critical systems. The construction incorporates Sun's floating style design which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing durability and performance consistency. The valve's specifications include a T2A cavity, Series 2 classification, and it requires an installation torque of between 45 - 50 lbf ft (61 - 68 Nm). It also has a hex size of 1-1/8 inches (28.6 mm). For maintenance or repairs, the seal kit compatible with this cartridge uses Viton components (990202006), ensuring high resistance to heat and chemicals. This robust design and specification make the CXFCXEN an excellent choice for hydraulic systems requiring precise fluid control with minimal leakage.
