The Sun Hydraulics CNJEXFV (CNJEXFV) is a high-performance check cartridge valve designed for hydraulic systems requiring reliable, pilot-to-close operation with a customizable bypass orifice. This valve features a spring-biased closed configuration that facilitates controlled flow from port 1 to port 2 while restricting flow in the reverse direction. It operates with a nominal pilot ratio of 1.8:1, meaning that pressure at the pilot port can effectively close the valve against higher pressures at port 1. The design integrates hardened steel seats, enhancing wear resistance and tolerance to contamination. Engineered for durability and performance, the CNJEXFV incorporates Sun's floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. This valve is suitable for applications where precise fluid control and reliability are paramount. Its capacity reaches up to 160 gpm (610 L/min), and it accommodates an orifice range between .016 - .354 inches (0.4 - 9 mm), allowing customization according to specific system requirements. For installation, the valve requires a hex size of 1 5/8 inches (41.3 mm) and an installation torque between 350 - 375 lbf ft (474 - 508 Nm). The use of Viton seals ensures compatibility with a wide range of fluids and enhances the operational longevity of the valve under various environmental conditions. This model is particularly suited for systems where equal pressure distribution across ports is necessary to maintain valve closure, ensuring efficient and safe hydraulic operations.

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.
