摘要： A method for coating a valve assembly including: providing a valve assembly including a metal susceptible to corrosion; cleaning an outside surface of the valve assembly; preparing a zinc primer by adding an anti-microbial agent to provide an anti-microbial zinc primer; applying a first layer of the anti-microbial zinc primer to the outside surface of the valve assembly; and applying a second layer over the first layer, the second layer including a topcoat for a two-layer coat; and curing the two-layer coat by heating the valve assembly. A valve assembly with protection layers including anticorrosion and antimicrobial protection is also described.

摘要： A valve assembly having a bolt with a through hole for a security wire includes at least one valve of the valve assembly mechanically coupled to a pipe or to a section of another component of the valve assembly by a coupling or by a pair of mating flanges. At least one hollow bolt is bolted through a closing bolt hole of the coupling or a joining bolt hole of the pair of mating flanges. The at least one hollow bolt accepts a safety wire run completely through the hollow bolt in a longitudinal direction of the hollow bolt and extending completely through the closing bolt hole of the coupling or the joining bolt hole of the pair of mating flanges.
