The Sun Hydraulics CNDEXAV (CNDEXAV) is a highly specialized pilot-to-close check cartridge valve designed for advanced hydraulic systems. This valve uniquely features a spring-biased closed mechanism with a customer-specified bypass orifice, ensuring tailored functionality for specific applications. It operates by allowing fluid flow from port 1 to port 2 while restricting flow in the reverse direction, with flow control facilitated through pressure interactions among its three ports. The pilot pressure at port 3 can close the valve against higher pressures at port 1, with a nominal pilot ratio of 1.8:1, indicating its efficiency in managing differential pressures up to 1800 psi (125 bar) when the pilot is pressurized to 1000 psi (70 bar). Additionally, the CNDEXAV is built with hardened steel seats that enhance its durability and resistance to wear and contamination. Its design incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding\u2014a common issue due to excessive installation torque or variations in cavity/cartridge machining. This valve is suited for systems requiring precise control over fluid handling and pressure regulation, particularly where temporary fluctuations in pilot pressure could impact performance. The technical specifications of the CNDEXAV include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 20 gpm (80 L/min), and an adjustable orifice range from .016 to .107 inches (0.4 to 2.7 mm). The valve's installation requires specific torque settings between 30-35 lbf\u00b7ft (41-47 Nm), ensuring secure and reliable operation within hydraulic circuits. This model's adaptability and robust construction make it ideal for complex hydraulic tasks where precision and reliability are paramount.

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.
