A welded bonnet gate valve made of forged steel is a high-performance valve designed for applications requiring secure sealing and durability under high-pressure and high-temperature conditions. The welded bonnet construction eliminates the risk of leakage by creating a permanent seal between the bonnet and the valve body, making it ideal for critical applications where safety and reliability are paramount. The forged steel body enhances the valve’s strength and resistance to wear, ensuring long service life in demanding environments. This gate valve provides efficient flow control with minimal pressure drop when fully open and a tight shutoff when closed. It is commonly used in industries such as oil and gas, petrochemical, and power generation, where robust and leak-proof valves are essential.
