Characteristics
The lug butterfly valve balances the compactness of the clamp valve with the stability of the single-sided flange connection. One end of it has an integral flange (lug), and the other end is a clamp type. During installation, only one side needs to be connected to the pipeline flange, and the other side needs to be fixed with a nut. This design eliminates the need for relying on flange alignment at both ends like clamp valves, making installation more convenient and reliable. It is particularly suitable for pipeline ends or situations that require frequent disassembly and maintenance, while avoiding stress issues that may arise from long bolt penetration. It is a preferred solution that balances space and stability requirements.
