The Sun Hydraulics CNDEXEV (CNDEXEV) is a sophisticated hydraulic valve designed for precise fluid control in various applications. This spring-biased, pilot-to-close check cartridge valve features a bypass orifice, which customers can specify to meet specific system requirements. The valve primarily facilitates flow from port 1 to port 2 while restricting the flow in the reverse direction. It operates with a nominal pilot ratio of 1.8:1, meaning that it requires a higher pressure at port 1 compared to the pilot port to remain closed, ensuring efficient operation under varying pressure conditions. The CNDEXEV is built with hardened steel seats, enhancing its durability and resistance to wear and contamination. This robust construction is complemented by Sun's floating style construction that reduces the risk of internal parts binding due to installation torque or machining variations of the cavity/cartridge. The valve's design allows it to maintain stability and reliability even with momentary decays or losses in pilot pressure, which could otherwise cause unintended opening. This model is suitable for systems requiring up to 20 gpm (80 L/min) capacity and can withstand a maximum operating pressure of 5000 psi (350 bar). Its compatibility with various orifice sizes ranging from .016 to .107 inches (0.4 to 2.7 mm) provides flexibility in application across different hydraulic setups. Installation specifications include a valve hex size of 7/8 inches (22.2 mm) and an installation torque between 30 - 35 lbf ft (41 - 47 Nm), ensuring easy integration into existing systems. Overall, the Sun Hydraulics CNDEXEV offers a reliable solution for managing hydraulic flow in systems where precise control and robust performance are critical.

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.
