2” throught 12” butterfly valve specifications.

Butterfly Valves are ideal for heavy duty applications such as fire protection, water treatment, food & beverage, pharmaceutical, mining, and many others.

Every valve is factory-tested to 110% of its pressure rating for optimum performance in the field.

The unique resilient seat is designed to seal against the disc, isolating the valve body and stem from the line.

*All torque values shown on chart are for “wet” (water and other non-lubricating media) on-off service. Under certain conditions, hydrodinamic torque can meet or exceed seating and unseating torques. When designing valve systems, hydrodynamic torque must be considered to help ensure correct selection or application.
