1, degreasing cleaning steps: valve nonfat components before assembly must go through the following process: 1) According to process requirements, part of the valve parts need polishing processing, surface can't be machining burrs, etc. ; 2) All Industrial Valves parts for degreasing process; 3) After the completion of the degrease pickling passivation ( Detergent containing phosphorus) ; 4) After pickling passivation with pure water is rinsed clean, cannot have pharmaceutical residues ( Carbon steel parts leave out this step) ; 5) Dry parts with non-woven fabric, each valve can't cable MAO retained components surface, or use a clean dry nitrogen; 6) With non-woven fabric or precision filter analysis of pure alcohol to wipe each Industrial Valves parts, until no dirty color. 2, skim the valve assembly requirements of nonfat components must be kept sealed valve is clean, for installation. Requirements for the installation process is as follows: 1) Skim the valve installation must ensure that the workshop clean, or clean up temporary area ( For example with the new purchase of striped cloth or plastic film, etc. ) To prevent the dust enters in the valve installation process. 2) The assembly workers must be dressed in a clean, pure cotton overalls, head Dai Chun cotton padded cap, hair can't leakage, foot wear clean shoes, hand wear plastic gloves ( Skim) 。 3) Erection tools must be conducted before the degreasing valve assembly degreasing cleaning, ensure clean.
are important in ensuring resilient gate valve, and the machine is utilised by everyone from resilient seated valve to os & y valve fire protection.
What are you waiting for? Don't you want to provide perfect support to cast iron valve? If yes, so, switch to resilient wedge gate valve right away!
Diversifying is an excellent growth strategy, as it allows Mech to have multiple streams of income that can often fill seasonal voids and, of course, increase sales and profit margins.
Although there are various available in the market (such as cast iron gate valve, resilient seal gate valve, and os&y valve), recent study results have made this y gate valve rising stem gate valve a preferred wedge valve choice of the people.
Natural has the distinct os&y gate valve which is irreplaceable.
