A Check Valve, also known as a non-return or one-way valve, is a mechanical device designed to control the flow of fluid within a system. Its purpose is to allow fluid to flow in one direction while preventing reverse flow. This function is achieved through the valve's design, which includes a hinged and spring-loaded mechanism that opens when fluid flows in the desired direction and closes to block the flow if it tries to reverse. Attributes:• Durability to withstand the cyclic stresses of opening and closing.• Maximum operating pressure 1000 psi (69bar).• Resistant to corrosion for a prolonged lifespan.• Ensures effective prevention of backflow, maintaining system efficiency and integrity. Applications: A Check Valve is used to connect to the fuel, engine oil, and coolant lines and their respective sensors to allow one-way fluid for accurate sensing data.
