    Shandong Ronborn Machinery Technology Co.,Ltd, with professional factory, is one of the leading China cast iron air valve manufacturers, we are able to offer you cheap cast iron butterfly valve. Welcome to wholesale products from us.

    Double orifice air valve that combines both large orifice & small orifice functions within one unit.The large orifice allows air to be expelled from the system during filling of a pipeline and admit air back into the system whenever sub-atmospheric pressure occurs.Air is vented from the system until water enters the valve and lifts the float against its seat,ensuring a tight seal.In the event of sub-atmospheric pressure in the system,the water level drops causing the float to fall from its seat and allow the admission of air.
    Product application:
    1.  The product specification 50mm to 200mm can be used in the environment of clean water, raw water and seawater, and the working pressure is 1.0/1.6/2.5/4.0Mpa, which can meet the design of rapid mass exhaust, secondary trace exhaust, water hammer protection and sewage backflow.
    2.  The exhaust valve is a full flow funnel body channel type design with a large diameter circular floating body and a self-sealing rubber ring lined with alloy steel plate.
