The Sun Hydraulics CNHEXBN (CNHEXBN) is a sophisticated hydraulic valve designed for precise flow control in fluid power applications. This spring-biased closed, pilot-to-close check cartridge valve features a bypass orifice whose diameter can be specified by the customer, accommodating a range of .016 to .252 inches (0.4 to 6.4 mm). It facilitates flow from port 1 to port 2 while restricting flow in the reverse direction, with pressure at port 2 directly opposing the pilot pressure. The valve's nominal pilot ratio of 1.8:1 ensures that a pressure of 1000 psi at the pilot port will close the valve against a pressure of 1800 psi at port 1. This feature is critical for applications requiring reliable operation under variable pressure conditions, as any decay or loss of pilot pressure could momentarily open the valve. The CNHEXBN incorporates hardened steel seats, enhancing its durability and contamination tolerance, making it suitable for environments where wear and particle intrusion are concerns. Sun Hydraulics' floating style construction is integrated into the design of the CNHEXBN, minimizing potential internal part binding due to excessive installation torque or variations in cavity/cartridge machining. This construction detail ensures consistent performance and longevity of the valve even under strenuous installation conditions. With a maximum flow capacity of 80 gpm (320 L/min) and installation torque requirements ranging from 150 to 160 lbf-ft (203 to 217 Nm), this valve is designed for high-capacity systems requiring precise hydraulic control. The use of Viton seals further enhances its performance by providing excellent resistance against high temperatures and chemical degradation. The CNHEXBN's robust design and customizable features make it an ideal choice for demanding hydraulic applications where precision and reliability are paramount.

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.
