How To Repair A Leaking Bronze Ball Valve?

Here are some instructions from a professional bronze ball valve supplier. First, it is necessary to find out that the upstream and downstream pipelines of the globe valve for sale have indeed relieved the pressure before the disassembly and decomposition operations can be carried out. When disassembling and reassembling, you must be careful to prevent damage to the sealing surface of the ball valve copper parts, especially non-metal parts. Special tools should be used when removing the O-ring. The bolts on the flange must be tightened symmetrically, gradually and evenly during assembly.

The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts and working medium (such as gas) in the ball valve, etc are compatible. When the working medium is gas, gasoline (GB484-89) can be used to clean metal parts. Clean non-metal parts with pure water or alcohol. The disassembled individual parts can be cleaned by dipping. Metal parts with undecomposed non-metal parts can be scrubbed with a clean, fine silk cloth impregnated with cleaning agent (to prevent fibers from falling off and adhering to the parts). When cleaning, all grease, dirt, glue, dust, etc. adhering to the wall must be removed.

Non-metal parts of the pex ball valve with bleeder should be taken out of the cleaning agent immediately after cleaning, and should not be soaked for a long time. After cleaning, it needs to be assembled after the cleaning agent of the washed wall surface is volatilized (can be wiped with a silk cloth not soaked in the cleaning agent), but it must not be left for a long time, otherwise it will rust and be contaminated by dust. New parts of the flanged bronze ball valve also need to be cleaned before assembly.

Use grease for lubrication. Grease should be compatible with ball valve metal materials, rubber parts, plastic parts and working medium. When the working medium is gas, special 221 grease can be used. Apply a thin layer of grease on the surface of the seal installation groove, apply a thin layer of grease on the rubber seal, and apply a thin layer of grease on the sealing surface and friction surface of the valve stem. When assembling, it should not be allowed to pollute, adhere to or stay on the surface of the gate valve for sale or enter the cavity with metal chips, fibers, grease (except those specified for use), dust, other impurities, and foreign objects.
