A bolted cover non-return valve made of forged steel is a durable and efficient valve designed to prevent backflow in pipelines, ensuring the unidirectional flow of fluids. The bolted bonnet construction provides a secure and leak-proof seal, while the forged steel material enhances the valve’s strength and resistance to high pressures and temperatures. This type of valve operates automatically, allowing fluid to flow in one direction and closing when reverse flow is detected, thus protecting equipment and maintaining system efficiency. Commonly used in industries such as oil and gas, petrochemical, and power generation, this valve is valued for its reliability, low maintenance, and ability to perform effectively in demanding environments.
