Application note
At DN400, the Butterfly Valve is typically specified for main headers and isolation duty. The butterfly valve pairs with Reguvale's standard range so engineers can standardize flanges, seats, and actuators across a plant.
FAQ
Which standard should I choose? Match the flange standard already used in your plant (ANSI here). Mixing standards causes leaky joints.
Can I get a different seat? Yes — EPDM, PTFE, and NBR seats are available depending on media and temperature.
