Plug connection of plug valve

Accumulation of hard slag,dirt,or any foreign matter in the pipeline can interfere with the efficiency of the plug valve and severely damage critical components of the valve.The inside of the pipe must be thoroughly cleaned with air or steam.When tapping a pipe,determine the size and length of the pipe threads to avoid filling the pipe with the seat and disc.
Thoroughly clean the ends of the threads to remove any harmful steel or iron deposits.If the weld is stronger when necessary,use a Teflon tape or pipe bond.Pipeline adhesives can only be used in small amounts on pipe threads,but pipe adhesives must never be used on valve threads.Do not allow any pipe bonding agent to flow into the valve body to avoid damage to the disc and seat.

Before installation,cut off the fluid passing through the plug valve to make the plug valve work properly.Completely close the plug valve before installation.Place the wrench on the hex head of the pipe close to the pipe to avoid possible deformation.After installing the plug valve,support the pipe:the drooping pipe will deform the plug valve and cause failure.
