How to use
Install the valve in the pipeline in the correct flow direction, ensuring the arrow on the valve body matches the intended flow. Secure the valve using appropriate thread or coupling methods for the existing piping material and size. After installation, pressurize the system and check for leaks and proper unidirectional operation by verifying that flow passes in the intended direction and that no reverse flow occurs when pumps stop.
Usage recommendations
When selecting and installing the ARCO VITAQ 6/4" check valve, confirm compatibility with the system's pressure and temperature ranges and use suitable sealing materials for the pipe connections. Periodic visual inspection and leak checks during routine system maintenance help ensure long-term reliable operation. In applications with high particulate content, consider upstream filtration to avoid wear or sticking of the valve mechanism.
