Butterfly Valve 30 to 144 inch with Bolted Seal (Series BFII)

Category:

The VSI Waterworks’ BFII Butterfly Valve is a workhorse for flow control and isolation service in-line sizes from 30” through 144”. The resilient seat is held on the body by corrosion resistant retainers, allowing easy adjustment at every seat interface. The seat is field replaceable on all valves, and in-line replaceable on larger sizes with proper safety precautions. Flow through discs assure minimal pressure drop. A standard ISO 5211 or MSS SP-101 actuator attachment bonnet make automation a painless experience. Valves in this line are designed and constructed to meet and exceed AWWA C504.
