The Sun Hydraulics COFCXEN (COFCXEN) is a precision-engineered hydraulic component designed for specific fluid control operations. This valve is a spring-biased closed, pilot-to-close check cartridge with a nominal pilot ratio of 1.8:1, facilitating controlled operations under varying pressure conditions. It primarily allows fluid flow from port 1 to port 2 while blocking reverse flow entirely, ensuring directional control and operational safety in hydraulic systems. The COFCXEN valve operates effectively up to a maximum pressure of 5000 psi (350 bar) and can handle flow rates up to 40 gpm (160 L/min). It features a T2A cavity and belongs to the Series 2 category, indicating its compatibility with specific hydraulic setups. The valve\u2019s design incorporates Sun's floating style construction which minimizes internal part binding\u2014this is crucial in maintaining valve integrity and performance despite installation torque variations or cavity/cartridge machining inconsistencies. One of the standout specifications of the COFCXEN is its maximum valve leakage rate, which stands at only 1 drop per minute (0.07 cc/min) at 110 SUS (24 cSt), showcasing its efficiency in maintaining system pressures without significant losses due to leakage. Installation specifications include a hex size of 1-1/8 inches (28.6 mm) and an installation torque range of 45-50 lbf.ft (61-68 Nm). The model weighs approximately 0.50 lb (0.25 kg). This valve is ideal for applications requiring reliable non-return functionality in hydraulic circuits where precise pressure management is critical. Its robust design ensures longevity and reliability even under challenging operating conditions, making it a valuable component for various hydraulic applications requiring high-performance check valves.

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.
