A gear operated bolted bonnet globe valve is a robust valve designed for precise flow control in industrial systems. It features a bolted bonnet, providing a secure and leak-proof seal, making it suitable for high-pressure and high-temperature applications. The valve is operated via a gear mechanism, which allows for easier operation, particularly in larger sizes or difficult-to-reach locations, compared to manual hand wheels. Available in flange end and buttweld connection types, the flange end version offers easy installation and maintenance, while the buttweld version provides a permanent, leak-tight connection, ideal for critical, long-term applications. These globe valves are commonly used in industries such as oil and gas, petrochemical, and power generation for their durability, reliable operation, and effective flow regulation in demanding conditions.
