The Sun Hydraulics COHCXZV (COHCXZV) is a high-performance hydraulic check valve designed to allow flow from port 1 to port 2 while effectively blocking reverse flow. This spring-biased closed, pilot-to-close check cartridge operates with a nominal pilot ratio of 1.8:1, meaning that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. The valve features an external pilot port where pressure opposes the pressure at port 1 by the same ratio, ensuring precise control and operation under varying pressures. The COHCXZV is characterized by its robust construction which includes Sun's floating style design that minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining. This feature enhances the reliability and longevity of the valve in demanding applications. The valve has a maximum operating pressure of 5000 psi and a capacity to handle up to 80 gpm (320 L/min), making it suitable for high-flow systems. Designed for stringent performance requirements, this model ensures minimal leakage, with maximum valve leakage specified at just one drop per minute. It also supports easy installation with a hex size of 1-1/4 inches and an installation torque range between 150-160 lbf ft. Weighing only 1.80 lbs, it is relatively lightweight yet durable, crafted to sustain rigorous industrial operations without compromise on performance. This model is particularly useful in applications where reverse flow prevention is critical and where precise hydraulic control is required under variable pressure conditions. Its design ensures that even with equal pressures at all ports, the valve remains closed, thereby providing reliable and secure operation in hydraulic circuits.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. The valve allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the external pilot port opposes pressure at port 1 at a ratio of 1.8:1. Port 3 is blocked.
- 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.
- Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
- 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.
