    Application note

    At DN400, the Pneumatic Butterfly Valve is typically specified for main headers and isolation duty. The pneumatic 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 (DIN 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.
