The Sun Hydraulics CNFEXDV (CNFEXDV) is a sophisticated pilot-to-close check cartridge valve designed for hydraulic systems requiring reliable, controlled flow. This valve facilitates the flow from port 1 to port 2 while effectively restricting flow in the reverse direction from port 2 to port 1. A notable feature of the CNFEXDV is its hardened steel seat, which enhances wear resistance and tolerance to contamination, ensuring durability and long-term performance in various applications. The valve operates with a nominal pilot ratio of 1.8:1, meaning that a pilot pressure of 1000 psi at port 3 can close the valve against a higher pressure of 1800 psi at port 1. This functionality is critical in applications where control over hydraulic flow under varying pressures is necessary. Additionally, the pressure at port 2 directly opposes the pilot pressure, contributing to the stability and responsiveness of the valve operation. Sun Hydraulics has incorporated their floating style construction into this model, minimizing potential internal binding that can occur due to excessive installation torque or variations in cavity/cartridge machining. This design consideration ensures consistent performance and ease of installation across different systems. The CNFEXDV offers flexibility in terms of customization with a customer-specified bypass orifice diameter, allowing for precise control tailored to specific system requirements. The allowable orifice range for this model spans from .016 to .127 inches (0.4 to 3.2 mm), accommodating a broad spectrum of flow capacities up to 40 gpm (160 L/min). The valve's robust design is complemented by its installation specifications, including a hex size of 1-1/8 inches (28.6 mm) and an installation torque range of 45-50 lbf ft (61-68 Nm).

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.
