The Sun Hydraulics COFCXDV (COFCXDV) is a pilot-to-close check cartridge valve, designed for hydraulic applications that require reliable, controlled flow. This model features a nominal pilot ratio of 1.8:1, allowing it to close against higher pressures 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 1800 psi at port 1. The valve ensures no reverse flow from port 2 to port 1 under any conditions and maintains closure with equal pressures at all ports. Constructed with Sun Hydraulics' floating style design, the COFCXDV minimizes internal part binding and potential damage caused by installation torque or variations in cavity/cartridge machining. It fits in a T2A cavity and belongs to the Series 2 category from Sun Hydraulics. This model can handle a maximum flow capacity of 40 gpm (160 L/min) and withstands up to 5000 psi (350 bar) in operating pressure. Key specifications include a maximum valve leakage rate of approximately one drop per minute at an oil viscosity of 110 SUS (24 cSt), indicating high sealing efficiency. The valve has an installation requirement with torque settings between 45 \u2013 50 lbf ft (61 \u2013 68 Nm) and features a hex size for installation measuring 1-1/8 inches (28.6 mm). Weighing just about .50 lb (0.25 kg), it provides robust performance in diverse hydraulic setups without adding significant weight to the system configuration. The recommended seal kit for this cartridge is made from Viton material, ensuring durable performance under varying operational conditions.
