1) Make sure that the piping and valves have been flushed before operation. 2) Valve operation: The valve stem is rotated according to the input signal of the actuator. When the valve is rotated 1/4 turn (90 °) forward, the valve is shut off. The valve opens when rotated 1/4 turn (90 °) in the reverse direction. 3) The valve is open when the direction arrow of the implementing agency is parallel to the pipeline; the valve is closed when the indicating arrow is perpendicular to the pipeline. Maintenance has a long service life and maintenance-free period, will depend on the following factors: normal working conditions, to maintain a harmonious temperature / pressure ratio, and reasonable corrosion data Note: The ball valve is closed, the valve body remains the same Presence of pressurized fluid ● Relief of line pressure and opening of the valve prior to service ● Disconnection of the power supply or air supply prior to service ● Removal of the actuator from the support prior to service ● Must ascertain that the upstream and downstream pipes of the ball valve have been unloaded Disassembly and disassembly can only be performed after pressure is removed. ● Disassembly and reassembly must be performed with care to prevent damage to the sealing surfaces of parts, especially non-metallic parts. Special tools should be used when removing o-rings. ● Bolts on flanges must be symmetrical, Tighten evenly ● The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts and working medium (such as gas) in the ball valve. Working medium for gas, gasoline (GB484-89) can be used to clean metal parts. Non-metallic parts cleaned with pure water or alcohol ● Disassembled individual parts can be cleaned by dipping. Non-metallic parts that remain undistracted may be cleaned with a clean, fine, silk-dipped cleaning cloth (to prevent the fibers from sticking to the parts). Cleaning must remove all the grease, dirt, glue, dust and other adhesion on the wall ● Non-metallic parts should be removed from the cleaning agent immediately after cleaning, not for a long time ● After cleaning, to be washed wall washer volatile (Can be used silk cloth wipers without cleaning agent) assembly, but should not be shelved for a long time, otherwise it will rust, dust pollution ● new parts also need to be cleaned before assembly ● use grease lubrication. Grease should be ball valve metal materials, rubber parts, plastic parts and working medium are compatible. When the working medium is gas, for example, special 221 grease. Apply a thin layer of grease on the surface of the seal mounting groove, a thin layer of grease on the rubber seal, and a thin layer of grease on the sealing surface and friction surface of the valve stem. ● Metal Debris, fibers, grease (except for the provisions of the use of) dust and other impurities, foreign bodies and other pollution, adhesion or stay on the surface of the parts or into the lumen.
