The Sun Hydraulics CNHEXBV (CNHEXBV) is a robust and versatile hydraulic valve designed for specific flow control applications. This spring-biased closed, pilot-to-close check cartridge valve features a bypass orifice whose diameter can be specified by the customer within an allowable range. It is engineered to allow flow from port 1 to port 2 while restricting flow in the opposite direction, making it suitable for systems where unidirectional flow is crucial. The valve operates with a nominal pilot ratio of 1.8:1, meaning that it can close against a higher pressure at port 1 when influenced by adequate pressure at the pilot port. This feature is particularly useful in maintaining control over hydraulic flows under varying pressure conditions. The direct opposition of pressures at port 2 and the pilot enhances its stability and response accuracy. Constructed with hardened steel seats, the CNHEXBV offers excellent wear characteristics and contamination tolerance, ensuring long service life and reliability even in harsh environments. It also incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. The valve's specifications include a maximum capacity of 80 gpm (320 L/min), with installation requiring specific torque settings (150-160 lbf ft/203-217 Nm) to ensure optimal performance. Additionally, it fits into a T17A cavity and is part of Sun Hydraulics' Series 3 lineup, reflecting its advanced design tailored for high-efficiency hydraulic systems. Overall, the CNHEXBV is engineered to meet demanding hydraulic control applications where precise flow regulation and valve performance are necessary. Its customizable features and robust construction make it a valuable component in industrial hydraulic 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.
