The Sun Hydraulics COFAXJE (COFAXJE) is a highly efficient and reliable spring-biased closed, pilot-to-close check cartridge valve. This valve facilitates fluid flow from port 1 to port 2 while preventing reverse flow under any condition, making it an ideal component for regeneration circuits. The nominal pilot ratio of 1.8:1 allows the valve to close against higher pressures at port 1 when appropriate pressure is applied at the pilot port, ensuring stable operation even with pressure fluctuations. Designed for maximum performance, the COFAXJE can handle up to 40 gpm (160 L/min) and withstands a maximum operating pressure of 5000 psi (350 bar). It features minimal internal leakage, rated at less than one drop per minute, which enhances its efficiency in hydraulic systems. The robust construction includes a T2A cavity and Series 2 compatibility, with installation specifications requiring a torque between 45-50 lbf ft (61-68 Nm) and a hex size of 1-1/8 in (28.6 mm). The cartridge\u2019s weight is modest at approximately .50 lb (0.25 kg), making it suitable for various applications without adding significant bulk. For enhanced durability in different environments, especially where corrosive elements are present, corrosion-resistant versions are available indicated by model code suffixes AP or LH. In summary, the Sun Hydraulics COFAXJE offers superior control in hydraulic systems with its reliable check functionality and robust design tailored for demanding applications where fluid control and prevention of reverse flow are critical.

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 pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuits.
- 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.
- In the begining the CO*A's did not have a positive seal on the pilot pistons and the CO*B's did. Now the CO*A's are positively sealed and the 2 valves are mechanically identical. CO*A's are more readily available and cost less.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION section). For further details, please see the Materials of Construction page under TECHNICAL RESOURCES.
- 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.
