The Sun Hydraulics CNJEXFN (CNJEXFN) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic applications requiring reliable flow control and check functionalities. This valve features a spring-biased closed configuration with a bypass orifice that can be specified by the customer within an allowable range of 0.4 to 9 mm. It is engineered to allow flow from port 1 to port 2 while restricting flow in the reverse direction, ensuring efficient operation in various hydraulic systems. The CNJEXFN incorporates hardened steel seats, enhancing its durability and resistance to wear, even in environments with high contamination levels. The nominal pilot ratio of 1.8:1 indicates that a pressure of 1000 psi at the pilot port will close the valve against a pressure of 1800 psi at port 1. This feature is crucial for applications where precise pressure control is necessary. Additionally, the valve's design includes Sun's floating style construction which minimizes internal part binding and potential damage due to installation torque or variations in cavity/cartridge machining. The valve fits within a T19A cavity and supports a maximum flow capacity of up to 160 gpm (610 L/min). Installation requires specific torque settings between 350 and 375 lbf ft (474 \u2013 508 Nm), ensuring secure and reliable assembly. Overall, the CNJEXFN offers robust performance for hydraulic systems requiring dependable backflow prevention and flow regulation under varying pressure conditions. Its customizable orifice size and strong construction make it suitable for a wide range of industrial applications.

This valve is a spring biased closed, pilot-to-close check cartridge with a bypass orifice. It incorporates a steel seat and is non-vented. The valve allows flow from port 1 to port 2 and restricts flow from port 2 to port 1. Pressure at the pilot (port 3) opposes pressure at port 1 at a ratio of 1.8:1. Pressure at port 2 directly opposes the pilot pressure. Note: The bypass orifice diameter is specified by the customer. See Technical Data below for the allowable orifice range.
- Features hardened steel seats for excellent wear characteristics and contamination tolerance.
- 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.
- 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.
