In the pharmaceutical, chemical and food industry a flange butterfly valve is used to interrupt product flow (solid, liquid, gas) within the process. The valves used in these industries are usually manufactured according CGMP guidelines (current good manufacturing practise).Butterfly valves generally replaced ball valves in many industries particularly petroleum due to lower cost and ease of installation, but pipelines containing butterfly valves cannot be 'pigged' for cleaning.

High Performance Butterfly Valves comply with API 609 Category B and can be used for shutoff and throttling control.They are designed to handle everything from general applications to viscous and corrosive liquids; corrosive gases and steam.

LUG type butterfly valve for cold, hot and drinking water, heating air, mineral oil as well as general industrial applications. Operation with manual grip or alternatively gearbox with hand wheel
