ABSTRACT:
A chemical fluid valve transfer (e.g., load/unload) assembly is formed from a male valve assembly and a female valve assembly. The male valve assembly is fitted with a male connector which houses a chamber that is connected to a flush inlet line, and a flush outlet line, and a chemical transport line. The female valve assembly is fitted with a female connector which mates with the male valve assembly male connector for interconnecting the male valve and female valve assemblies, and fitted with a chemical transport line. Another aspect of the present invention is a method for transferring a chemical fluid between a tanker fitted with a female coupler and a fill/unload station fitted with a male coupler and hose assembly. This method involves the connecting of the tanker hose and the fill station hose with the valve assembly described above. Next, the male and female connectors and said chamber are purged with liquid or gaseous cleaning fluid admitted via the flush inlet flush line and withdrawn via the flush outlet line. One of the male valve assembly or the female valve assembly then is opened to permit the chemical fluid to enter into the chamber for withdrawal therefrom via the flush outline line for its sampling. Finally, the chemical fluid is transferred between the tanker and the fill station through the valve assembly.
