Compact Flange Ball Valve

The ultra-compact flange ball valve is a new-generation short face-to-face design developed through localized Italian technology, domestically known as "Italian-style ball valve" and "Q71F-16P wafer-type ball valve". Featuring integrated flanges, it directly replaces conventional flange ball valves.

With ISO-standard high platform body, compatible with pneumatic/electric actuators and accessories: position feedback, mechanical/smart positioners for automated process control.
