How to use
To operate the valve, rotate the blue handle ninety degrees relative to the pipeline to close the flow completely. Align the handle parallel to the pipe to open the valve and allow unrestricted media flow. Ensure the installation is performed by a qualified professional using appropriate thread sealants to prevent leaks at the 3/8 inch male-female connection points. Regular manual operation of the valve at periodic intervals helps prevent mineral buildup and ensures smooth movement over time.
What to consider before purchase
Verify that your piping system requires a 3/8 inch male-female threaded connection before purchasing.
Check available space in your installation area to confirm that the compact mini design fits your layout requirements.
Ensure the operating pressure and temperature of your system align with standard brass ball valve capabilities.
Confirm that your local plumbing regulations permit the use of brass components for your specific water supply or heating project.
Usage recommendations: Periodically inspect the valve connections for any signs of moisture or leakage, and operate the blue handle a few times a year to maintain optimal mechanical movement and prevent seizing.
