In this application, the Vortex Orifice Gates were designed for shutting off a silo handling polycarbonate pellets. The gates were destined for Asia to be installed in a coastal location with a tropical climate. Due to the coastal environment the customer needed the gates to be fully made from stainless steel and Vortex also supplied the gate with an epoxy coated air cylinder. The valves were supplied with Festo 24VDC air controls and magnetic reed switches.
