Use of grease lubrication. Grease and ball Industrial Valves should be metal material, rubber parts, plastic parts and working medium are incompatible. Besmear in seal installation groove on the surface of a thin layer of grease, apply a thin layer of grease on rubber seal, valve stem seal face and friction surface coated with a thin layer of grease. Assembly time should not be allowed to have metal scraps, fiber dust, grease and other impurities, foreign bodies, such as pollution, adhesion, or stay on the parts surface, or into the lumen. Only pay attention to the accuracy of the various aspects hard seal ball valve to the normal use of machinery. Use hard seal ball Industrial Valves, to achieve the maximum effectiveness, you need to pay attention to in the use of some with the details. Such as hard seal ball valve closed, pneumatic compression of still exist inside the valve body fluid. Before repair, remove line pressure and the valve is in open position; Disconnect the power supply or source; The actuator and stand out. Must first find out on the ball valve, the downstream piping have indeed after unloading the pressure, to carry out dismantling operations. Decomposition and assembly again when the sealing surface of the parts, must be careful to prevent injury especially non-metal parts, o-rings inappropriate use of special tools. Assembly the flange bolts must be symmetrical, step by step, to tighten evenly. Cleaning agents should be with the rubber ball valve parts, plastic parts, metal parts and working medium are incompatible. Break down the single parts can use dip way to clean. When cleaning should remove all adhesion on the surface of grease, dirt, plastic product, dust, etc. Non-metallic parts after cleaning shall be immediately removed from cleaner, may soak for a long time. The new parts also need to be cleaned before assembly.
