Bonomi DA8101-4 Butterfly Valve 4 Inch With Actuator

The Bonomi DA8101-4 is a 4-inch, lug-style, high-performance butterfly valve built with a carbon steel body and a CF8M stainless steel disc, using a carbon-filled PTFE seat to deliver tight shutoff in demanding industrial piping. It arrives with a Valbia DA75V double-acting pneumatic actuator, enabling precise, rapid quarter-turn control of flow. This assembly is designed for ANSI Class 150 flange connections and supports actuator supply pressures up to 116 psi, making it suitable for water and oil-service lines while not recommended for corrosive media. As part of Bonomi’s Series 8101, the DA8101-4 combines valve and actuator in a compact package with lug-style construction that simplifies installation and maintenance. Typical applications include process piping and water treatment where reliable, precise flow control is required in industrial systems.
