Product Overview
API Cryogenic Globe Valve is an industrial globe valve with an extended bonnet, designed for shut-off control in LNG, liquid oxygen, liquid nitrogen and other cryogenic pipeline systems.
Product Features
Extended bonnet keeps the packing sealing area away from cryogenic media.
Low-temperature carbon steel or stainless steel pressure-retaining parts are suitable for LNG and other cryogenic services.
Extended stem travel allows normal disc operation under cryogenic conditions.
Valve cavity design helps reduce residual cryogenic media before pipeline shutdown.
