The Sun Hydraulics COHCXAN (COHCXAN) is a sophisticated hydraulic valve designed for precise fluid control in various applications. This spring-biased closed, pilot-to-close check cartridge features a nominal pilot ratio of 1.8:1, ensuring 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 facilitates flow from port 1 to port 2 while securely blocking any reverse flow from port 2 to port 1 under all conditions. Equipped with Sun's floating style construction, the COHCXAN minimizes potential internal part binding, which can result from excessive installation torque or variations in cavity/cartridge machining. This design enhances the reliability and longevity of the valve in demanding operational environments. The valve is designed for use in T17A cavities and belongs to Series 3. The COHCXAN can handle up to 80 gpm (320 L/min) with a maximum operating pressure of 5000 psi (350 bar). It ensures minimal leakage, not exceeding one drop per minute, even under high-pressure conditions. The hydraulic integrity is further ensured by Viton seals provided in its seal kit (990017006), known for their high performance and compatibility with various fluids. This model has an installation torque requirement between 150 -160 lbf ft (203 -217 Nm) and weighs approximately 1.80 lbs (0.80 kg). With its robust construction and precise engineering, the COHCXAN is an ideal choice for applications requiring reliable non-return functionality with external pilot control capabilities.
