The Sun Hydraulics CNHEXDN (CNHEXDN) is a highly specialized hydraulic valve designed for precise fluid control in various hydraulic systems. This spring-biased closed, pilot-to-close check cartridge valve features a bypass orifice, which customers can specify based on their system requirements. The allowable orifice range is from 0.4 mm to 6.4 mm, accommodating diverse applications and enhancing customization. The CNHEXDN is engineered with hardened steel seats that offer superior wear characteristics and contamination tolerance, ensuring long-term reliability and performance under harsh conditions. The nominal pilot ratio of 1.8:1 implies that a pilot pressure of 1000 psi can close the valve against a higher pressure of 1800 psi at port 1, demonstrating its robust capability in maintaining system stability. This valve operates by allowing fluid flow from port 1 to port 2 while restricting flow in the reverse direction, which is critical for controlling the movement of hydraulic fluids accurately. It integrates Sun\u2019s floating style construction that minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining, thus enhancing operational consistency and reducing maintenance needs. Designed for use in the T17A cavity and part of the Series 3 line-up, the CNHEXDN has a maximum capacity of 80 gpm (320 L/min), making it suitable for high-flow applications. Installation requires specific torque settings between 150 to 160 lbf\u00b7ft (203 to 217 Nm), ensuring secure fitting without damaging the valve. Additionally, it utilizes Viton seals (part number: 990017006) for excellent chemical resistance and durability under varying temperatures. Overall, the Sun Hydraulics CNHEXDN valve stands out for its customizable features, robust construction, and reliable performance in controlling hydraulic flows effectively within industrial systems.

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.
