HFI is a high pressure float valve with internal liquid measuring device. The float valve is designed for direct flange mounting or welding on to plate heat exchanger type condensers. HFI is direct acting, therefore no differential pressure is required to activate the valve. HFI is robust and reliable due to its simple design. The float valve is equipped with a purge valve for purging non condensable gases e.g. air from the top of the valve housing. This feature is also useful if the valve has to be serviced. The HFI is available with two external connections on the housing for drainage and pressure equalizations.
