439-4777: 1 3/16" X 1 3/16" Check Valve

Description: A Check Valve is a mechanical component used in fuel lines to ensure that fuel flow in one direction only, from the fuel tank to the engine. It prevents fuel from flowing back into the tank when the engine is not running or is turned off, thereby reducing the risk of leaks, spills, and other potentially hazardous situations. The Check Valve in fuel lines is typically made from materials that are resistant to gasoline, diesel fuel, and other petroleum-based fuel. Attributes: • Maximum operating temperature of the valve is 180° C. • Helps to maintain fuel pressure. Applications: A Check Valve is used to provide a unidirectional flow of fuel from the fuel tank to the engine, mostly used in Cat 793F, 794, 795F, 796, and 798 Truck, C175-16 Engine (Piston), D1500, DE1500S, and DE1675 Generator Set.
