· Align Connecting Pipes

Ensure the connecting pipes from both ends of the valve are properly aligned.

Support the valve to avert unnecessary stresses induced by the connecting pipes.

Typically, most threaded ball valve units can hardly absorb any gaps.

Thus, any form of distortion in pipes tend to influence valve functionality and tightness of the connection.

While at it, ensure you confirm that the valve rating is compatible with the projected service conditions.

Operate the threaded ball valve from a fully open to a closed position.

· Apply Sealant on Connection Ends

Ensure to use recommended thread sealants when making up connections.

Additionally, follow the sealant’s manufacturer directions for proper use.

However, you should install it on the pipe and not necessarily on the valve.

· Secure the Valve

Now it’s time to tighten the ball valve on the respective pipe connector ends.

But you must be cautious enough not to over-tighten the valve on the pipe.

If it is over-tighten, there is a possibility of distorting the internal ball valve parts, torque transmission, or stress into the body joint.

While at it, you also need to take caution never to loosen the body to tailpiece connection.

This may happen as a result of reverse rotation or counter-rotation during alignment or installation.

Such loosening can easily compromise body to tailpiece sealing.

· Confirm Whether Installation Process is Correct

After you complete the installation process, ensure you counter-check to verify the packing nut’s tightness after installation.

It is the ideal way to be confident of the threaded ball valve’s high performance.
