The Sun Hydraulics CNJEXZN (CNJEXZN) is a spring-biased closed, pilot-to-close check cartridge valve equipped with a bypass orifice, which allows customization based on specific customer requirements. This valve is engineered to facilitate fluid flow from port 1 to port 2 while restricting the flow in the opposite direction. It features a unique pilot ratio of 1.8:1, meaning that it requires a higher pressure at port 1 compared to the pilot port to remain closed, ensuring reliable operation under varying pressure conditions. The CNJEXZN model incorporates hardened steel seats that offer superior wear resistance and tolerance to contamination. This durability makes it suitable for applications where longevity and minimal maintenance are critical. The valve's design includes Sun\u2019s floating style construction which helps prevent internal parts from binding, a common issue that can occur due to over-torquing during installation or discrepancies in cavity/cartridge machining. This valve is designed for use in hydraulic systems with a maximum capacity of 160 gpm (610 L/min), and it accommodates a wide range of orifice sizes from .016 to .354 inches (0.4 to 9 mm), allowing for flexible application across various hydraulic functions. The specified valve hex size for installation is 1 5/8 inches (41.3 mm), and the recommended installation torque ranges between 350 and 375 lbf ft (474 - 508 Nm). For maintenance, Viton seal kits are available under part number: 990019006. Overall, the Sun Hydraulics CNJEXZN check cartridge offers robust performance and flexibility, making it an ideal choice for hydraulic systems requiring reliable check functionalities with customizable flow characteristics.

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.
