Fuel Emergency Cut off Shear Valve for Submersible Fuel Dispenser
- A fuel emergency cut-off shear valve—also known as a crash valve or impact valve—is a mandatory safety device installed beneath a fuel dispenser in pressurized systems. Its primary purpose is to instantly stop the flow of fuel from a pressurized line (such as one fed by a submersible turbine pump) if the dispenser is dislodged by a vehicle collision or exposed to fire.
