A hand wheel operated bolted bonnet gate valve is a manually controlled valve designed for reliable flow control in industrial pipelines. It features a bolted bonnet that ensures a tight and secure seal, making it suitable for high-pressure and high-temperature applications. The valve is operated using a hand wheel, which raises or lowers the gate to allow or block the flow. It is available in two connection types: flange end and buttweld. Flange end valves are easy to install and maintain, while buttweld valves provide a permanent, leak-proof connection for demanding applications. These valves are widely used in industries such as oil and gas, power, and water treatment for their durability, efficiency, and leak-tight performance.
