]]> VSI Waterworks’ Series BFI Butterfly Valves

The VSI Waterworks’ BFI Butterfly Valve is an AWWA butterfly valve, designed to be an economical flow control solution for line sizes of 2” through 30”.

The body is fully lined with resilient material to match the line media’s properties, allowing no media-to-body contact. The concentric design features a one piece shaft, which is available in a variety of materials and pinned to a standard ductile iron or stainless steel disc. The streamlined disc guarantees low cavitation and high valve coefficients.

Valves in this line are designed and constructed to meet and exceed AWWA C504.

]]> VSI Waterworks’ Series BFVI Butterfly Valves

The VSI Waterworks’ BFVI Butterfly Valve is a workhorse for flow control and isolation service in-line sizes from 24” 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.

Stem design: Available in square shaft for easy mounting of actuators, levers and gear operators.
Top flange: Conforms to ISO 5211 for the mounting of actuators, levers and gear operators.
One piece shaft: Maintains disc position.
Blow-out proof shaft: Guarantees shaft containment, and leak mitigation, in the case of extreme failure situations
Shaft pins: Enables a vibration free connection between the shaft and the disc.
Bushings: High performance PTFE bushings provide correct alignment of shaft through the body and reduces torque. Stainless steel reinforcement prevents creep and compression in high temperature applications.
Stem seal: Positive seal in both directions to prevent leakage.
Disc edge: Smooth finished disc edge provides superior seal, reduces valve torque and provides bubble tight shutoff.
Bi-directional body & seat design: Suitable for bi-directional use at full rated pressure.
100% tested: Every valve is fully in VSI’s ISO 9001 facility to ensure performance and reliability. The body is hydrostatically tested to 1.5 times pressure rating. The seat is tested to 1.1 times pressure rating and at 50psi to ANSI Class VI zero leakage. Every valve is serialized and test report is available.
