The JH-11B automatic nozzles are specially designed for self-service pre-pay card-lock systems to prevent gasoline spills. These nozzles remain closed until the pumping system is pressurized and automatically close when the pressure is released, ensuring a secure shut-off when placed back on the dispenser. With accurate flow control, customers can precisely fill their tanks to the desired level, making it easy to stop the fuel flow at any time.
