The Sun Hydraulics CNHEXCN (CNHEXCN) is a meticulously engineered pilot-to-close check cartridge valve designed for precise hydraulic control. This valve features a spring-biased closed configuration and includes a bypass orifice, the diameter of which can be specified by the customer to meet specific application requirements. The allowable orifice range spans from 0.4 mm to 6.4 mm, providing flexibility in hydraulic flow management. The CNHEXCN valve is designed to allow flow from port 1 to port 2 while restricting flow in the reverse direction, ensuring efficient operation in hydraulic circuits. It incorporates a steel seat for enhanced durability and resistance to wear, even in environments with high contamination levels. The nominal pilot ratio of 1.8:1 indicates that the valve can close against higher pressures at port 1 when appropriately piloted from port 3, making it suitable for various pressure modulation tasks. This model also benefits from Sun's floating style construction which reduces the risk of internal parts binding due to installation torque or machining variations of the cavity/cartridge interface. It is compatible with T17A series cavities and can handle up to 80 gpm (320 L/min) capacity, making it robust enough for substantial hydraulic systems. Additionally, this valve requires an installation torque between 150 and 160 lbf ft (203 - 217 Nm) and uses Viton seals for reliable performance under varying operational conditions. Its hex size is standardized at 1-1/4 inches (31.8 mm), ensuring easy installation with common tools. Overall, the CNHEXCN is an essential component for systems requiring reliable check functionality with pilot control capabilities in demanding industrial applications.

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.
