The CSA RFP technology can be considered like some sort of air bag for pipelines and is based on the purpose of ensuring unrestricted flow of air in during vacuum, to provide the same degree of protection of a standard air valve during critical operations like pipe draining, burst of pump failure with the forth functions or RFP mechanism being triggered only in case of excessive air out flow, to prevent the valve from being slammed shut from water during the closing phase. RFP can be used everywhere except for those sections of the pipe where column separation may occur and exposed to severe negative pressure conditions.<\/p>\n
