How to use
Install the valve inline in the pipe run following the indicated flow direction. Ensure compatible thread or coupling types are used for the 1" connections and apply appropriate sealing (PTFE tape or thread sealant) on threaded joints. After installation, pressurize the system gradually and check for leaks around connections. Periodically inspect the valve for external signs of wear or leakage and verify one-way operation by observing flow behaviour during system operation.
Usage recommendations
Do not expose the valve to aggressive chemicals or media outside its intended use. For installations in heating systems, protect the valve against freezing and prolonged dry operation. When servicing, isolate the section of the system, depressurize and drain before removing the valve. Follow local plumbing regulations and standards for installation and maintenance.
