ABSTRACT:
An isolation and flow control valve in a furnace charging installation, installed in a discharge conduit of a storage hopper which may be alternately at ambient pressure for loading and furnace pressure for discharging, is characterized by a valve member which is caused to move serially in two directions during opening and closing. The movement is produced by an actuator mechanism including a pivot arm and a cam system and results in movement axially with respect to the conduit for seating and unseating and generally transverse to the conduit axis for controlling material flow through the conduit.
