The Sun Hydraulics CNDEXBN (CNDEXBN) is a sophisticated spring-biased closed, pilot-to-close check cartridge valve, designed specifically for hydraulic applications where flow direction control and pressure regulation are crucial. This model features a bypass orifice, the diameter of which can be specified by the customer to suit specific application needs within an allowable range of 0.016 to 0.107 inches (0.4 to 2.7 mm). The CNDEXBN operates with a nominal pilot ratio of 1.8:1, indicating that it requires a higher pressure at the pilot port relative to port 1 to maintain closure\u2014specifically, a pressure of 1000 psi (70 bar) at the pilot port can close the valve against a pressure of 1800 psi (125 bar) at port 1. Constructed with hardened steel seats, the CNDEXBN excels in wear resistance and is highly tolerant to contamination, enhancing its durability and reliability in demanding environments. The valve's design incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This feature ensures consistent performance and longevity of the valve even under varied installation conditions. The CNDEXBN has a maximum operating pressure capacity of 5000 psi (350 bar) and can handle flow rates up to 20 gpm (80 L/min). Its compatibility with Viton seal kits further underscores its suitability for challenging operational conditions where high thermal and chemical resistance is required. The valve's dimensions include a hex size of 7/8 inches (22.2 mm) and an installation torque requirement between 30 - 35 lbf ft (41 - 47 Nm), making it adaptable for various hydraulic setups while ensuring easy maintenance and serviceability.

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.
