The Sun Hydraulics COBGXCV (COBGXCV) is a robust pilot-to-close check cartridge valve, designed for effective operation in regeneration circuits. This valve ensures controlled flow from port 1 to port 2 while completely blocking reverse flow under any condition, thereby enhancing system reliability and performance. With a nominal pilot ratio of 1.8:1, the valve requires a specific pressure at the pilot port to close against higher pressures at port 1, maintaining stability even with slight variations in pilot pressure. Constructed to handle a maximum operating pressure of 5000 psi (350 bar) and a capacity of up to 10 gpm (40 L/min), the COBGXCV is suitable for high-pressure applications. It features hardened steel seats which offer excellent wear resistance and tolerance to contamination, ensuring longevity and consistent performance. The valve's internal components are protected by Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. For maintenance or repairs, the valve supports Viton seal kits (part number: 990163006), facilitating easy servicing. Additionally, its compact design with a weight of just .20 lb (0.10 kg) simplifies integration into various hydraulic systems without adding significant weight or bulk. Installation requires a torque of between 20 - 25 lbf ft (27 - 33 Nm), and it features an internal hex size of 5/16 in. (8 mm). Despite its high capacity and robust construction, the COBGXCV maintains minimal leakage with maximum leakage rates at around 1 drop/min (0.07 cc/min), ensuring efficient operation without significant fluid loss.

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.
