For DN50, this configuration is common in skids and branch lines where space is tight. 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 (API 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.
