The Sun Hydraulics CNDEXEN (CNDEXEN) is a robust pilot-to-close check cartridge valve designed for high-performance hydraulic systems. This valve features a spring-biased closed mechanism, allowing fluid flow from port 1 to port 2 while restricting flow in the reverse direction from port 2 to port 1. It operates with a nominal pilot ratio of 1.8:1, which means pressure at the pilot port needs to be significantly lower than at port 1 to keep the valve closed, specifically, 1000 psi at the pilot can hold against up to 1800 psi at port 1. The CNDEXEN is distinguished by its hardened steel seats that provide superior wear characteristics and tolerance to contamination, enhancing durability and reliability in tough environments. The design incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining, ensuring consistent operation and reducing maintenance requirements. This valve is equipped with a customer-specified bypass orifice ranging from .016 inches to .107 inches (0.4 mm to 2.7 mm), allowing customization according to specific system requirements. It supports a maximum operating pressure of up to 5000 psi (350 bar) and has a capacity of up to 20 gpm (80 L/min). The valve's installation requires specific torque settings between 30 and 35 lbf-ft (41 - 47 Nm) and uses a Viton seal kit for enhanced sealing performance under various conditions. Overall, the Sun Hydraulics CNDEXEN check cartridge is an essential component for hydraulic circuits requiring precise control over flow direction and pressure management, suitable for applications needing reliable performance under high pressure and adverse 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.
