The Sun Hydraulics CNFEXEN (CNFEXEN) is a high-performance, pilot-to-close check cartridge valve designed for robust hydraulic applications. This valve features a spring-biased closed configuration and includes a bypass orifice, the diameter of which can be specified by the customer within an allowable range. It ensures reliable operation by allowing fluid flow from port 1 to port 2 while restricting flow in the reverse direction. The pressure at pilot port 3 needs to oppose the pressure at port 1 with a nominal pilot ratio of 1.8:1, meaning that higher pressures can be controlled effectively. The CNFEXEN is constructed with hardened steel seats, which provide excellent wear characteristics and contamination tolerance. This durability is crucial in maintaining valve integrity and performance over time. The valve's design incorporates Sun's floating style construction to minimize internal part binding and potential malfunctions due to excessive installation torque or variations in cavity/cartridge machining. This model is suitable for systems requiring up to 40 gpm (160 L/min) capacity and operates efficiently even with equal pressures at all ports, maintaining its closed state. The specified installation torque for this valve ranges from 45 to 50 lbf ft (61 to 68 Nm), ensuring a secure fit within its T2A cavity type and Series 2 configuration. Overall, the Sun Hydraulics CNFEXEN offers precise control in hydraulic systems, making it an ideal choice for applications requiring reliable check functionalities under variable pressure 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.
