Pneumatic ball valve maintenance matters needing attention

(1) you must first find out the pneumatic ball valve, the downstream piping have indeed after unloading the pressure, to carry out dismantling operations.
2 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.
(3) when the assembly on the flange bolts must be symmetrical, step by step, to tighten evenly.
(4) cleaner should with pneumatic ball valve of rubber parts, plastic parts, metal parts and working medium ( For example, gas) Are incompatible. Working medium is gas, cleaning metal parts available petrol. Non-metallic parts clean with clean water or alcohol.
5] break down individual parts can use dip way to clean. Still left did not break down the non-metallic metal parts can be fine clean clean immersion cleaner silk ( In order to avoid fall off fiber adhesion on zero parts) Scrub. When cleaning, please remove all adhesion on the surface, plastic product, dust, oil and dirt.
[6] non-metallic parts shall be immediately removed from the cleaning agent, after cleaning may soak for a long time.
once after wash wall cleaning agent to volatilize and after cleaning, Available not soak cleaner silk cloth to wipe) Are assembled, but shall not be shelved for a long time, or it will rust and dust pollution.
being new parts also need to be cleaned before assembly.
'levies use grease lubrication. Grease and pneumatic ball valve should be metal material, rubber parts, plastic parts and working medium are incompatible. Working medium of gas, available such as grease. Besmear in seal installation groove on the surface of a thin layer of grease, apply a thin layer of grease on the rubber seals, pneumatic valve stem seal face and friction surface coated with a thin layer of grease. ⑽ assembly time should not be allowed to have metal chips, fiber, fat ( With the provisions of the exception) Dust and other miscellaneous quality, foreign bodies, such as pollution, adhesion, or stay on the parts surface, or into the lumen.
