A bolted cover non-return valve is designed to allow unidirectional flow of fluids, preventing backflow in industrial systems. The bolted cover construction ensures a secure and leak-proof seal, making the valve suitable for high-pressure and high-temperature applications. This valve 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-tight connection, ideal for critical and long-term applications. These valves are widely used in industries such as oil and gas, power, and water treatment, where reliable prevention of backflow and durability are essential for safe and efficient operations.
