How to Install Thread Ball Valves?

The Threaded ball valve is a kind of ball valve. The connection between the valve and the pipeline is threaded. (BSPT, BSP, NPT, etc.).

It is mainly used for low-pressure, small-diameter pipelines with nominal pressure PN16-140 and nominal size DN8-DN100.

The ball valve could be in vertical or horizontal pipe runs. They are bi-directional therefore, the flow direction is not critical; In principle, the ball valve installation has no direction. Still, in the actual building, the ball valve body is usually connected to the tank’s direction or material to prevent excessive leakage between the valve body and the valve cover. The best practice is to set up the valve handle to point in the direction of flow whenever possible.

Turn off the water supply: Before you start the installation, turn off the water supply to the area where you will be installing the valve.

Prepare the pipe: Clean the ends of the tube where you will be attaching the valve. Use a pipe cutter or hacksaw to make a clean, straight cut.

Apply thread sealant: Apply thread sealant to the male threads of the valve. This will help to ensure a watertight seal.

Attach the valve: Attach the valve to the pipe by screwing it onto the male threads. Tighten the valve using a pipe wrench or pliers, being careful not to overtighten and damage the thread.

Check the valve orientation: Ensure the valve is in the correct orientation. Ball valves have an arrow on the body indicating the direction of flow. Make sure the arrow is pointing in the direction of the flow.

Turn on the water supply: Turn on the water supply and check the valve for leaks. If you notice any leaks, tighten the valve a little more until the leaks stop.

Test the valve: Once the valve is securely attached, turn it on and off to make sure it functions properly.

That’s it! Your thread ball valve should now be installed and ready to use.
