Quzhou Hipsen Vehicle Parts Co., Ltd
About Yuchai sapre parts, we have valves. There are fuel cut off valve and fuel stop solenoid valve. A fuel shutoff solenoid is an electronic switch that automatically stops the fuel flow from the tank to the engine. The valve is normally in the open position; however, a loss of electrical power to the valve or activating a switch in the vehicle closes the valve to stop fuel flow. The fuel shutoff solenoid is located in the fuel pump, but the electronic switch is inside of the driver's compartment. Once the switch is activated, the flow of fuel stops, and the engine no longer operates. Many of these switches also have a manual override feature to shut off the fuel in the event of a power failure. The solenoids are useful in stopping fuel flow in the event of an accident.
