The Sun Hydraulics COJCXDV (COJCXDV) is a high-performance, pilot-to-close check cartridge valve designed for advanced hydraulic systems requiring reliable one-way flow control. This valve allows fluid to flow from port 1 to port 2 while blocking any reverse flow from port 2 to port 1, ensuring operational stability and safety. The valve features a nominal pilot ratio of 1.8:1, which means that it can close against a higher pressure at port 1 when the appropriate pressure is applied at the pilot port. Specifically, a pressure of 1000 psi at the pilot port will close the valve against a pressure of up to 1800 psi at port 1. The COJCXDV is equipped with Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing its durability and performance consistency. It also has a maximum operating pressure capacity of 5000 psi and can handle flows up to 160 gpm. The valve's design ensures minimal leakage (maximum leakage at 110 SUS is approximately one drop per minute), which is critical for maintaining system efficiency and effectiveness. Furthermore, this model utilizes Viton seals for high temperature and chemical resistance, ensuring long service life even under harsh conditions. The installation torque required ranges between 350 -375 lbf ft, and the valve's hex size is standardized at 1-5/8 inches for compatibility with typical installation tools. Weighing in at approximately 2.60 lb, the COJCXDV combines robust construction with precise engineering to deliver reliable performance in various hydraulic applications.
