A Fuel Line Check Valve is designed to control the flow of fuel through the unit and prevent reverse flow or backflow. It is typically located in the fuel line between the fuel filter and the engine and consists of a valve mechanism that allows fuel to flow in one direction while preventing or restricting the flow in the opposite direction. The primary purpose is to maintain fuel pressure and prevent fuel from flowing back into the tank.Attributes:• The normal flow capacity of the valve is 7.6 liters per minute, which ensures an adequate amount of fuel reaches the engine• The hexagonal shape of the valve provides a secure grip and increased torque Applications:A Fuel Line Check Valve acts as a safety mechanism and a flow control valve in Fuel Filter Lines.
