The Sun Hydraulics COHCXCV (COHCXCV) is a high-performance, spring-biased closed, pilot-to-close check cartridge valve designed for hydraulic systems requiring reliable, controlled flow. This model operates with a nominal pilot ratio of 1.8:1, meaning it can close against significantly higher pressures at port 1 when controlled pressure is applied at the pilot port. Specifically, 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. The COHCXCV features an innovative floating style construction that minimizes potential internal binding caused by excessive installation torque or variations in cavity/cartridge machining. This design ensures smooth operation and enhances the durability of the valve. It is engineered to fit a T17A cavity and belongs to Series 3, capable of handling up to 80 gpm (320 L/min) with maximum operating pressures up to 5000 psi (350 bar). Additionally, it exhibits minimal leakage, not exceeding one drop per minute at a fluid viscosity of 110 SUS (24 cSt). This model comes equipped with Viton seals for enhanced performance under varying temperature conditions and chemical exposures typical in complex hydraulic systems. The valve's robust construction includes a hex size of 1\u00bc inches (31.8 mm) and requires an installation torque between 150 and 160 lbf ft (203 -217 Nm). With its weight approximately around 1.80 lb (0.80 kg), the COHCXCV is both compact and manageable for integration into various hydraulic setups without compromising on reliability or efficiency.
