This hopper fill valve is designed for mounting directly to a hopper to allow for diversion of material into the hopper while simultaneously venting the conveying air back to the destination (or a remote) filter for venting. This valve is also commonly known as a scale fill valve in that it does allow for accurate delivery of material from a pneumatic conveying system (pressure or vacuum) into a scale hopper.
