The Sun Hydraulics COJCXFN (COJCXFN) is a high-performance hydraulic valve designed for precise control in fluid power applications. This spring-biased closed, pilot-to-close check cartridge valve facilitates controlled flow from port 1 to port 2 while completely blocking reverse flow from port 2 to port 1 under any condition. It features a nominal pilot ratio of 1.8:1, meaning it requires a significantly lower pilot pressure to close against higher pressure at port 1, enhancing its efficiency and reliability in maintaining system stability. The valve is engineered with Sun's floating style construction which minimizes the risk of internal parts binding, a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This design feature ensures consistent and reliable operation even under challenging installation conditions. With a maximum operating pressure capacity of up to 5000 psi (350 bar) and a flow capacity of up to 160 gpm (610 L/min), the COJCXFN is suited for heavy-duty applications. It also boasts minimal leakage, with maximum valve leakage specified at around 1 drop/min (0.07 cc/min), ensuring that the hydraulic systems maintain their integrity and performance over time. Additionally, the valve's robust construction includes a hex size of 1-5/8 in (41.3 mm) and an installation torque range of 350 \u2013 375 lbf\u00b7ft (474 \u2013 508 Nm), providing ease of installation while maintaining durability and resistance against operational stresses. The model weighs approximately 2.60 lb (1.20 kg), making it sturdy yet manageable for various setups. For maintenance or repairs, a Viton seal kit is available under part number: 990019006, ensuring long-term usability and performance retention of this essential hydraulic component.

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 external pilot port opposes pressure at port 1 at a ratio of 1.8:1. Port 3 is blocked.
- 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.
- With equal pressures at all ports the valve is closed.
- 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.
