Poppet Valve Assembly With In-Line Sight Glass

摘要

A poppet valve assembly is provided for use on a fuel tanker truck which enables the truck's driver to determine whether fuel is present in the valve assembly. The valve assembly has a housing which has a sight glass secured therein. The sight glass is visible through cut-outs in the housing. If the driver observes liquid in the valve assembly, the driver may drain the valve assembly to avoid spilling the liquid prior to opening the poppet valve assembly. When the poppet valve assembly is opened, vapor flows through a flow channel in the poppet valve assembly.
