Fly Ash Storage Bin Valves
Fly ashes from the boiler systems in the pulp manufacturing are stored in bins, which are shut off in the bottom with an isolation valve. This valve allows the isolation of the rotary feeder valve / screw feeder. The fly ashes are fed through the rotary feeder and the screw feeder into a dump truck for disposal of the fly ashes.
The isolation valve has to deal with an abrasive material, which increases the internal friction in the valve, which does not allow a standard knife gate or O-port valve to function properly. Friction reduction and increased actuation force are necessary to have a well functioning valve for the isolation of the fly ash storage bins.
Stainless Valve Company has developed a Stargate O-Port® valve, which meets these requirements. It is supplied with a hydraulic actuator and a hydraulic power pack. Below is an example of such a Stargate O-Port® valve.
