The Sun Hydraulics COJCXFV (COJCXFV) is a meticulously engineered hydraulic valve designed for efficient flow control in hydraulic systems. This spring-biased closed, pilot-to-close check cartridge valve uniquely features a 1.8:1 pilot ratio, facilitating precise control by allowing flow from port 1 to port 2 while securely blocking reverse flow. It operates under a maximum pressure of 5000 psi (350 bar) and can handle up to 160 gpm (610 L/min), making it suitable for high-capacity operations. The valve\u2019s design includes an external pilot port where pressure assists in closing the valve against higher pressures at port 1, maintaining stability even with variations in pilot pressure. This feature ensures reliable operation under fluctuating pressures, which is critical for maintaining system integrity and preventing leaks\u2014characterized by a maximum leakage rate of only 1 drop/min (0.07 cc/min). The COJCXFV also benefits from Sun\u2019s floating style construction which helps prevent internal parts binding, a common issue caused by excessive installation torque or cavity/cartridge machining variations. Its robust construction is complemented by 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), ensuring secure and straightforward installation while minimizing potential damage during setup. Weighing at approximately 2.60 lbs (1.20 kg), the COJCXFV combines lightweight design with high durability, suitable for various hydraulic applications requiring reliable backflow prevention and fluid control under diverse operating conditions.

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.
