JFlow’s fugitive emission was designed to an additional sealing chamber for fugitive emission leakage and detection from the stem of the valve. The test port design allows a sniffer to detect any emission from the bonnet. This will protect people and the environment. The bonnet has an ISO direct mount pad on both sides for easy assembly to save on installation time. The 2 sets of SS 301 spring washer, V-ring packing, thrust washer and O-ring will seal the valve. The valve side of the fugitive emissions bonnet has a gasket as an additional seal. The bonnet will also act as an extended stem.
