ABSTRACT:
A valve for controlling the flow of particulate material through a conduit which may be referred to as a clam shell valve including and arcuate valve plate. The valve includes a seal block having a recess for receiving the leading edge of the valve plate to assure a seal between the conduit and the valve element. The seal block is shaped to inhibit the entrance of material into the seal block and allow for the easy discharge of that material on opening of the valve element. The valve also includes an upper wiper seal element for cleaning the surface of the valve.
