The Sun Hydraulics COBGXDV (COBGXDV) is a specialized check cartridge valve designed for hydraulic systems requiring precise flow control and prevention of reverse flow. This model features a spring-biased closed, pilot-to-close configuration with a nominal pilot ratio of 1.8:1, which means that it requires a higher pressure at the pilot port relative to the pressure at port 1 to close the valve effectively. Specifically, a pressure of 1000 psi at the pilot port will close against a pressure of 1800 psi at port 1. The valve facilitates flow from port 1 to port 2 while blocking any reverse flow from port 2 to port 1 under all conditions. Constructed with hardened steel seats, the COBGXDV offers excellent wear characteristics and high contamination tolerance, enhancing its durability and reliability in various applications. It is particularly useful in regeneration circuits where such properties are crucial. The valve's design includes Sun's floating style construction which minimizes potential internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. The COBGXDV operates with a maximum capacity of 10 gpm (40 L/min) and can handle pressures up to 5000 psi (350 bar). It ensures minimal leakage, not exceeding one drop per minute, maintaining system efficiency and performance integrity. Installation specifications include an internal hex size of 5/16 inch (8 mm) and an installation torque range between 20 - 25 lbf ft (27 - 33 Nm). This model weighs approximately .20 lb (0.10 kg), making it compact yet robust for industrial applications requiring precise hydraulic control.
