APl Pressure Seal Bonnet Swing Check Valve

Specifications

As the professional manufacturer, we would like to provide you Taian APl Pressure Seal Bonnet Swing Check Valve. And we will offer you the best after-sale service and timely delivery.Pressure self-tightening sealing: The higher the system pressure, the tighter the pressure sealing gasket (graphite ring, octagonal ring or delta ring) between the valve cover and the valve body is pressed, and the probability of leakage actually decreases. The weight advantage is that it is 20-30% lighter than the bolt valve cover structure of the same specification, saving pipeline support. The valve cover of APl Pressure Seal Bonnet Swing Check Valve can be lifted upwards as a whole without having to cut the valve off the pipeline. ; Full bore, rounded corner transition, low pressure drop, and reduced water hammer. Preferred horizontal pipelines; When installed vertically, the medium must flow upward
