The Sun Hydraulics CODBXZN (CODBXZN) is a sophisticated check valve designed for hydraulic systems requiring reliable, unidirectional flow control. This valve operates by allowing fluid to pass from port 1 to port 2 while preventing any reverse flow from port 2 to port 1 under all conditions. It features a nominal pilot ratio of 1.8:1, meaning that it can close against higher pressures at port 1 when influenced by appropriately scaled pilot pressure at the pilot port. Specifically, a pilot pressure of 1000 psi can close the valve against a pressure of 1800 psi at port 1. The CODBXZN's design incorporates Sun Hydraulics' floating style construction which helps prevent internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. This ensures smoother operation and enhances the longevity of the valve in demanding applications. The valve is primarily used in regeneration circuits where precise control over flow and direction is critical. Key technical specifications include a maximum operating pressure of 5000 psi, a capacity of up to 20 gpm, and minimal leakage at high viscosity, with only about one drop per minute at 110 SUS (approximately equivalent to 24 cSt). The valve's installation requires specific torque settings (30-35 lbf ft) and uses Viton seals for enhanced durability under various operational conditions. Overall, the Sun Hydraulics CODBXZN check valve is an essential component for hydraulic systems where high reliability and performance are necessary, especially in applications involving complex fluid direction and pressure regulation tasks.
