The high performance butterfly valve delivers heavy-duty,
automatic throttling control flow to applications involving
large flow rates and moderate pressure drops. It combines two
basic features of the high performance valve types:
a PTFE, RTFE, or metal seal ring that reduces seal friction and operating
torque, delivering increased performance over standard valves.
Low torque, double offset disc improves control and reduces seal wear
on longer operating cycles, reducing maintenance.
Rugged guiding supports long-term shut-off and throttling accuracy.
The flangeless, or single flanged construction option reduces size
and weight, simplifying installation and piping requirements.
High Cv ratings support high capacity capability at low pressure differentials.
