Chinese Forged Steel Bolted Bonnet Gate Valve Manufacturer

A Bolted Bonnet Forged Steel Gate Valve is a robust and durable type of forged steel gate valve designed for high-pressure and high-temperature applications. Its unique construction features a bonnet and body connected by bolts, ensuring a secure and leak-proof seal. These valves are sealed with spiral wound gaskets, making them easy to maintain and ideal for demanding industrial environments.

Our Bolted Bonnet Forged Gate Valves are engineered to meet the needs of small-diameter pipelines, with pressure ratings ranging from Class 150 to 2500 LB. They are capable of operating in temperatures from -29°C to 425°C for carbon steel models and up to 500°C for stainless steel variants. These valves are designed to either shut off or connect the flow of medium in pipelines, making them versatile for a wide range of applications. Depending on the material selected, they can handle various media, including water, steam, oil, nitric acid, acetic acid, oxidizing agents, urea, and more.

Key Design Features
