The Sun Hydraulics CNFEXBV (CNFEXBV) is a high-performance, spring-biased closed, pilot-to-close check cartridge valve that efficiently manages hydraulic flow with precision. Designed to allow flow from port 1 to port 2 while restricting flow in the opposite direction, this valve features a unique pilot ratio of 1.8:1. This means that a pilot pressure of 1000 psi can close the valve against a higher pressure of 1800 psi at port 1, ensuring reliable operation under varying pressure conditions. The CNFEXBV is built with hardened steel seats which offer exceptional wear resistance and tolerance to contamination, making it suitable for demanding applications. The valve's design includes a bypass orifice whose diameter can be specified by the customer, providing flexibility in application and installation. The allowable range for the orifice diameter spans from 0.016 inches to 0.127 inches (0.4 mm to 3.2 mm), accommodating various operational requirements. Incorporating Sun's floating style construction, the CNFEXBV minimizes internal parts binding that can occur due to excessive installation torque or variations in cavity/cartridge machining. This feature enhances the durability and reliability of the valve in diverse hydraulic systems. With a maximum capacity of 40 gpm (160 L/min), and an installation torque requirement between 45 to 50 lbf ft (61 to 68 Nm), this model is designed for robust performance in hydraulic circuits requiring precise flow control and check functionalities. The CNFEXBV uses Viton seals (part number: 990202006) for enhanced chemical resistance and operational longevity under harsh conditions.

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.
