The Sun Hydraulics COHCXCN (COHCXCN) is a high-performance spring-biased closed, pilot-to-close check cartridge valve. Designed for hydraulic applications, this valve facilitates controlled flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1 under all conditions. The COHCXCN 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. This feature ensures reliable operation even in scenarios where there is decay or temporary loss of pilot pressure. Key specifications include a maximum operating pressure of 5000 psi and a flow capacity up to 80 gpm. The valve's construction incorporates Sun\u2019s floating style design which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. Furthermore, the valve is designed for easy installation with a hex size of 1\u00bc inches and requires an installation torque between 150 - 160 lbf\u00b7ft. This model also boasts minimal leakage, maintaining tight control with less than one drop per minute at 110 SUS (approximately 24 cSt). Weighing at approximately 1.80 lbs, the COHCXCN is robust yet compact enough for versatile implementation in various hydraulic systems without compromising performance. The use of Viton seals ensures compatibility with a wide range of fluids and enhances the durability and reliability of the valve in diverse operating environments.
