Welded Cover Non Return Valve (Forged Steel)

A welded non-return valve made of forged steel is a durable and efficient valve designed to allow unidirectional fluid flow while preventing backflow in high-pressure and high-temperature systems. The welded bonnet construction ensures a permanent, leak-proof seal between the valve body and bonnet, making it suitable for critical applications where reliability and safety are paramount. The forged steel body enhances the valve’s strength, durability, and resistance to wear, enabling it to perform effectively in demanding environments. This valve operates automatically, closing to prevent reverse flow and protecting equipment from damage. It is widely used in industries such as oil and gas, petrochemical, and power generation, where robust and leak-proof valves are essential for system integrity.
