The Sun Hydraulics CNHEXAV (CNHEXAV) is a high-performance hydraulic valve designed for efficient flow control in hydraulic systems. This spring-biased closed, pilot-to-close check cartridge valve features a bypass orifice whose diameter is customizable according to customer specifications. It operates by allowing fluid flow from port 1 to port 2 while restricting flow in the reverse direction, with pressure at the pilot port 3 opposing pressure at port 1 at a nominal pilot ratio of 1.8:1. This valve is engineered with hardened steel seats, enhancing its durability and tolerance to contamination. The design ensures reliable operation even under conditions of pressure decay or loss at the pilot port, which might otherwise lead to unintended valve opening. The innovative Sun floating style construction minimizes internal part binding that could result from excessive installation torque or variations in cavity/cartridge machining. The CNHEXAV fits into a T17A cavity and belongs to the Series 3 category, with a maximum flow capacity of 80 gpm (320 L/min). Its operational parameters include an orifice range of .016 to .252 inches (0.4 to 6.4 mm), and it requires an installation torque between 150 and 160 lbf-ft (203 - 217 Nm). For maintenance and repairs, it utilizes a Viton seal kit designated as part number 990017006. This valve's robust construction and precise operational characteristics make it suitable for applications requiring reliable directional control and pressure management in hydraulic circuits.

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.
