The Sun Hydraulics COBGXFV (COBGXFV) is a spring-biased closed, pilot-to-close check cartridge valve designed to facilitate flow from port 1 to port 2 while blocking reverse flow under any condition. This valve functions with a nominal pilot ratio of 1.8:1, meaning that a pressure at the pilot port will effectively oppose and close against higher pressures at port 1. Specifically designed for regeneration circuits, the COBGXFV incorporates features such as hardened steel seats which enhance wear resistance and contamination tolerance. The valve's construction utilizes Sun's floating style to reduce risks of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It has a maximum operating pressure capability of 5000 psi (350 bar) and allows a flow capacity of up to 10 gpm (40 L/min). The COBGXFV ensures minimal leakage, with maximum valve leakage specified at 1 drop per minute (0.07 cc/min). Installation requires specific torque settings between 20 - 25 lbf ft (27 - 33 Nm) and the model weighs approximately .20 lb (0.10 kg). This product does not support reverse flow from port 2 back to port 1, ensuring unidirectional operation. Additionally, it is essential for users to maintain pilot pressure as any decay or loss could momentarily allow the valve to open. This robust design and specific operational characteristics make the COBGXFV an effective component in hydraulic systems requiring reliable one-way flow under various pressure conditions.
