Single poppet emergency shut-off valves are installed on fuel supply lines under dispensers to minimize collision and fire hazards at the dispenser. Often referred to as the "impact valve," it is designed to shut off the flow of product in the event of a dispenser impact or a fire involving the dispenser.

WARNING:

This valve requires periodic inspection to ensure the shut-off mechanism is operating correctly. Always shut-off the power to the dispenser when changing filters or doing maintenance. This valve is not intended to be used as a "block valve" and should not be opened under pressure. Opening under pressure can damage or distort internal components.
