Description
The Schneider Electric (Barber Colman) AV-93 is a cam and plunger-style, non spring return actuator engineered specifically for use with 1½” and 2″ VB-7xxx Series valves. Designed for commercial HVAC hydronic and steam systems, this actuator delivers precise, dependable valve positioning in heating and cooling applications where a non spring return (floating or on/off) control action is required.
As part of the trusted Barber Colman legacy — now carried forward under the Schneider Electric brand — the AV-93 is built to integrate seamlessly with the VB-7xxx valve body series, making it an ideal replacement or upgrade component for building automation and commercial controls systems.
