Neles™ three lever valve for Air Separation Units (ASU), series BH

Inherently safe valve to prevent pressure shocks in absorber beds

Neles lever valves are designed to air separation unit air inlet shut-off valve. They feature self-locking safety design for a specified differential pressure. The lever arrangement provides valve operation with low friction. The sealing sections are not subjected to abrasion wear, resulting in extremely low torque level.
