Points to Note During the Use of a Ball Valve The ball valve should be relieved of pressure and the valve in the open position prior to servicing.
Disconnect the power or air supply before servicing the ball valve.
Remove the actuator from the bracket before servicing.
Firstly, it is necessary to find out that the upper and lower pipes of the ball valve are actually relieved of pressure before they can be disassembled and disassembled. When disassembling or reassembling, care must be taken to prevent the sealing surface of the damaged parts. Especially for non-metallic parts, when using O-rings, special tool ball valve assembly method should be used. The bolts on the blue must be tightened symmetrically, stepwise and evenly.
The cleaning agent should be compatible with the rubber parts, plastic parts, electric single seat control valve metal parts and working medium in the ball valve. When the working medium is gas, the metal parts can be cleaned with gasoline. Non-metallic parts can be cleaned by dipping in a single part that has been cleaned with pure water or alcohol. Metal parts that have been left undecomposed by non-metallic parts can be scrubbed with a clean and fine cloth impregnated with a cleaning agent (to prevent the fibers from falling off and sticking to the parts). When cleaning, remove all non-metallic parts such as grease, dirt, glue, dust, etc. that adhere to the wall. Immediately after cleaning, remove the cleaning agent from the cleaning agent. Do not immerse for a long time and then wait for the wall cleaning agent to be volatilized. The cloth is not dipped in the cleaning agent, but it should not be left for a long time, otherwise it will rust and be contaminated by dust. The new parts should also be cleaned and greased before assembly. Grease should be compatible with ball valve metal materials, rubber parts, plastic parts and working media. When the working medium is gas, for example, special 221 grease can be used. Apply a thin layer of grease to the surface of the seal mounting groove, apply a thin layer of grease to the rubber seal, and apply a thin layer of grease to the sealing surface and friction surface of the valve stem. Dust, fiber, grease (except for the use of specified) dust and other impurities, foreign matter, etc., contaminate, adhere or stay on the surface of the part or enter the cavity
