The Sun Hydraulics CNFEXEV (CNFEXEV) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic systems requiring reliable, directional flow control. This valve facilitates fluid flow from port 1 to port 2 while effectively restricting flow in the reverse direction. It features a pilot ratio of 1.8:1, meaning that a pressure of 1000 psi at the pilot port will close the valve against a pressure of 1800 psi at port 1. The unique design includes a spring-biased closed mechanism with a customer-specified bypass orifice, allowing for customization based on specific system requirements. Constructed with hardened steel seats, the CNFEXEV offers exceptional wear characteristics and contamination tolerance, ensuring long service life and consistent performance under harsh conditions. The valve's capacity is rated at 40 gpm (160 L/min), suitable for various medium to high-flow applications. It also incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or cavity/cartridge machining variations. This model uses Viton seals for enhanced chemical resistance and durability across different operating environments. With its robust design and flexible specifications, including an adjustable orifice range from .016 to .127 inches (0.4 to 3.2 mm), the CNFEXEV is an ideal choice for applications requiring precise control over hydraulic flow and pressure management within complex hydraulic circuits.

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.
