The Sun Hydraulics COJCXZN (COJCXZN) is a spring-biased closed, pilot-to-close check cartridge valve designed for hydraulic systems. This model features a nominal pilot ratio of 1.8:1, meaning it requires a significantly higher pressure at port 1 to overcome the pilot pressure and open the valve. 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 is engineered to allow flow from port 1 to port 2 while blocking reverse flow under any condition, ensuring reliable operation and preventing backflow. Constructed with Sun's floating style design, the COJCXZN minimizes potential internal part binding that can occur due to excessive installation torque or variations in cavity/cartridge machining. This feature enhances the durability and longevity of the valve in demanding environments. The model is fitted into a T19A cavity and belongs to Series 4, with an impressive capacity of up to 160 gpm (610 L/min). It can handle a maximum operating pressure of up to 5000 psi (350 bar) and has a very low maximum valve leakage rate at specific conditions. The COJCXZN also incorporates several design specifications for ease of use and maintenance, including a hex size of 1-5/8 inches (41.3 mm) and an installation torque range between 350 - 375 lbf.ft (474 - 508 Nm). Weighing approximately 2.60 lb (1.20 kg), this model is robust yet manageable for system integration. It utilizes Viton seals for enhanced performance under varying operational conditions, ensuring reliability and efficiency in controlling fluid flow within hydraulic circuits.

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.
