Emergency shut-off valves are installed on fuel supply pipelines beneath dispensers at grade level to minimize hazards associated with collision or fire at the dispenser. If the dispenser is pulled down or moved by collision, the top of the valve breaks off at the integral shear groove, activating poppets and shutting off the flow of fuel.
Single-poppet models shut off supply flow, while double-poppet models shut off supply as well as prevent release of fuel from the dispenser's internal piping.
Valve inlet (bottom) connections are female pipe threads and outlet (top) connections are available with female threads, male threads or a union fitting.
