The Sun Hydraulics CODDXHN (CODDXHN) is a high-performance, pilot-to-close check cartridge valve designed for rigorous hydraulic applications. This model features a spring-biased closed configuration that ensures reliable operation by allowing flow from port 1 to port 2 while completely blocking reverse flow from port 2 to port 1 under any condition. The valve operates with a pilot ratio of 20:1, where pressure at the pilot port (port 3) counteracts the pressure at port 1 effectively and efficiently. Constructed with a poppet design, the CODDXHN significantly minimizes leakage of stored fluid from the accumulator, ensuring system integrity and reducing fluid loss. This valve is engineered to accommodate a maximum operating pressure of up to 5000 psi (350 bar), making it suitable for high-pressure applications. Additionally, it features Sun's floating style construction which helps prevent internal parts binding that might occur due to excessive installation torque or cavity/cartridge machining variations. The valve's specifications include a capacity equivalent to a .109 in. (2.8 mm) diameter orifice and an extremely low maximum leakage rate at only 1 drop per minute (0.07 cc/min). It is designed for installation using a hex size of 7/8 in. (22.2 mm) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). For maintenance or replacement purposes, it uses Viton seals as part of its seal kit/cartridge system. Overall, the Sun Hydraulics CODDXHN check valve is an essential component for systems requiring precise hydraulic flow management and leak prevention in demanding environments.
