The Sun Hydraulics COJCXEV (COJCXEV) is a robust pilot-to-close check cartridge valve with a specific design that allows flow from port 1 to port 2 while completely blocking reverse flow. It features a nominal pilot ratio of 1.8:1, meaning it requires a relatively lower pressure at the pilot port to close against higher pressure at port 1, enhancing its efficiency in fluid control operations. The valve\u2019s operation is influenced by pressures at the external pilot and port 2 areas, which directly oppose each other. Designed for high-capacity systems, this valve can handle up to 160 gpm (610 L/min) and withstands a maximum operating pressure of 5000 psi (350 bar). It ensures minimal leakage, not exceeding 1 drop/min. or approximately 0.07 cc/min., even under maximum pressure conditions. The COJCXEV is constructed using Sun\u2019s floating style design which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations, ensuring reliable performance and durability. The installation specifications include a valve hex size of 1-5/8 in. (41.3 mm) and an installation torque ranging between 350 - 375 lbf ft (474 - 508 Nm). Weighing in at approximately 2.60 lb (1.20 kg), the model is compact yet sturdy enough for demanding applications. The seal kit for this cartridge uses Viton components, known for their chemical resistance and suitability in high-temperature environments, further enhancing the valve's operational reliability and longevity in various hydraulic systems.

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.
