In thermal power plant, after dust catcher, fly ash of boiler is sent to ash storeroom by positive pneumatic conveying method. Valve is indispensable in this system. Flashboard and seal surface sustains high speed medium grain and air current abrading; traditional valves made by metal and plastic have very short using life which badly affected the reliability and economy of pneumatic conveying system. For a long time, researchers are longing for valve of pneumatic ash removal system with advanced technology, low maintenance cost and reliability; furthermore, installer and repairer need valves with low maintenance cost and easy-to-repair. Wearable engineering ceramic valve (series) can meet all these demands.
Mainly used for: silo pump outlet valve, pipeline switch valve and balance valve.
