Nozzle Check Valve: A nozzle check valve is a type of non-return valve designed to allow fluid flow in one direction while preventing backflow, using a streamlined, spring-assisted disc mechanism that operates within a nozzle-shaped body. It is engineered for high performance, fast closing response, and minimal pressure drop, making it ideal for critical flow applications in industries such as power generation, oil and gas, petrochemical, and water treatment. The key feature of a nozzle check va
