Request Information
Favorite
Metso's Neles BO series Butterfly Valve is designed for use in vacuum Pressure Swing Adsorption plants (VPSA), under extreme demanding conditions due to the high cycle and high tightness requirement. 

The series BO valve is a wafer type, soft seated, high performance, single eccentric disc valve. 

The valve is designed to last huge amounts of fast cycles, maintaining the internal tightness. 

Additionally it provides long lasting tight shut off with excellent flow characteristics and high capacity. 

The BO series fulfils the requirements of both ASME and EN/DIN standards.
