The Sun Hydraulics COBGXEN (COBGXEN) is a high-performance check cartridge valve, designed for specific hydraulic applications where control and prevention of reverse flow are critical. This spring-biased closed, pilot-to-close check cartridge operates with a nominal pilot ratio of 1.8:1, allowing for precise control by opposing pressure at port 1 with pilot pressure at a nearly 2:1 ratio. Specifically, the valve facilitates flow from port 1 to port 2 while completely blocking any reverse flow from port 2 to port 1 under all conditions. Constructed with hardened steel seats, the COBGXEN offers exceptional wear characteristics and contamination tolerance, enhancing its durability and reliability in various operational environments. The valve is engineered to handle a maximum operating pressure of up to 5000 psi (350 bar) and supports a flow capacity up to 10 gpm (40 L/min). Additionally, it features Sun's floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This valve\u2019s design also includes a robust seal kit made from Viton, ensuring optimal performance under diverse conditions. The COBGXEN model is primarily utilized within regeneration circuits due to its efficient control capabilities. It ensures minimal leakage, with maximum leakage defined at approximately 1 drop per minute (0.07 cc/min), thereby maintaining system integrity and performance. The installation process is facilitated by an internal hex size of 5/16 in (8 mm) and recommended torque specifications ranging between 20 - 25 lbf ft (27 - 33 Nm), ensuring secure and correct installation without over-tightening. Weighing just about .20 lb (0.10 kg), the COBGXEN combines compact design with robust functionality for specialized hydraulic applications.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. The valve allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuits.
- Features hardened steel seats for excellent wear characteristics and contamination tolerance.
- Product is not available with A and B spring ranges (4 and 15 psi (0,3 and 1 bar)).
- Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 1800 psi (125 bar) at port 1. Any decay or loss of pilot pressure could allow the valve to open, even if it is a momentary decay or loss.
- Pressure at the port 2 area directly opposes pilot pressure.
- Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
