▏Frequently Asked Questions

What are the working pressure ratings for the Lug Type Butterfly Valve Model BV-07 across different sizes?

The Lug Type Butterfly Valve Model BV-07 is engineered to deliver exceptional performance across various industrial pipeline configurations. Specifically, sizes ranging from 2 inches up to 12 inches are rated for a maximum working pressure of 200 PSI, making them highly suitable for moderate to high-pressure fluid control requirements. For larger pipeline installations spanning from 14 inches to 24 inches, the working pressure rating is optimized at 150 PSI. These pressure thresholds ensure robust structural safety and reliable sealing performance across diverse municipal water treatment and heavy industrial fluid management systems.
