FAQ

What is a flanged butterfly valve used for?

A flanged butterfly valve is commonly used for shut-off and flow control in water treatment, municipal infrastructure, HVAC systems, industrial utility lines, and general process pipelines.

What is the difference between a flanged butterfly valve and a wafer butterfly valve?

A flanged butterfly valve uses a flanged body connection and is often preferred for larger sizes or projects requiring a more robust installation method.

A wafer butterfly valve is more compact and is installed directly between pipe flanges.

What seat materials are available for a flanged butterfly valve?

Common seat options include EPDM, NBR, and PTFE.

Final seat material selection depends on the medium, temperature, pressure rating, and service requirements.

Can a flanged butterfly valve be supplied with an actuator?

Yes. Worm gear, pneumatic, and electric actuator configurations are available according to project control requirements.

What media is this flanged butterfly valve suitable for?

It is generally suitable for water, air, general service fluids, and mildly corrosive media.

Final material selection should be confirmed according to the actual working condition.

Can you provide customized sizes or flange standards?

Yes. Customized sizes, materials, seat types, flange standards, and actuation packages can be supplied according to project requirements.
