The Sun Hydraulics CNJEXEV (CNJEXEV) is a sophisticated pilot-to-close check cartridge valve designed for hydraulic systems requiring reliable non-return functionality. This model features a spring-biased closed configuration with a bypass orifice whose diameter can be specified by the customer, allowing customization to specific system requirements. The valve facilitates flow from port 1 to port 2 while restricting flow in the reverse direction, ensuring controlled operation under varying pressure conditions. The CNJEXEV operates with a nominal pilot ratio of 1.8:1, meaning that it can close against higher pressures at port 1 when the appropriate pressure is applied at the pilot port (port 3). This feature is particularly useful in applications where control over fluid flow direction and prevention of backflow are critical. The valve's design incorporates hardened steel seats which provide exceptional wear resistance and tolerance to contamination, enhancing durability and reducing maintenance needs. Engineered for high-capacity systems, this valve supports up to 160 gpm (610 L/min), making it suitable for use in large-scale hydraulic circuits. The construction of the CNJEXEV utilizes Sun\u2019s floating style to minimize internal parts binding, which could occur due to variations in cavity or cartridge machining or excessive installation torque. For installation, a hex size of 1 5/8 inches (41.3 mm) and a torque range of 350 - 375 lbf ft (474 - 508 Nm) are recommended. This valve is versatile enough to be used in various hydraulic applications where precise fluid control and reliability are paramount. Its ability to be custom-fitted with different orifice sizes (.016 - .354 in/0.4 - 9 mm) provides further adaptability to meet diverse operational demands within hydraulic systems.

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.
