GB Flange Butterfly Valve

Purpose and Characteristic

Hard seal butterfly valve series products,is my company's new development of long-life, eneray-savina butterflv valve. Products comply with national standards JB/T8527-2015 (metal sealed butterfly valve) and GB/T13927-2008 (general valve pressure test) standards and other relevant standards of the valve This product is composed of main parts, such as valve body, butterfly plate, sealing ring, transmission mechanism and so on. The structure of the two-dimensional or three-dimensional eccentric principle design, a new machining process of hard and soft sealing multi-level compatible, butterfly valve in the operation, reduce the torque, achieving the function of saving, energy saving. So as to ensure the overall corrosion resistance, high temperature and wear resistance of the butterfly valve.Its main performance characteristics are:

1. Uniaue structure. small size. light.flexible operation.labor-savina and convenient;
2. Sealed reliable,can meet alllevels of standards; 
3. The flow characteristic is good, and has the adjustment function;
4.  The use of eccentric principle, so that the close cover of zero wear and tear, to extend the servicelife of the valve;
5.  Wide range of applications,can be used in water, steam, oil, air, gas and other media;
6. Applicable to different temperature and 15.0MPa below the pressure level, corrosion resistance and other conditions of the pipeline.

Purpose

Our butterfly valve can be applied to food, medicine, petrolem and chemical industry, electric plant, steel plant, industrial environmental protection water treatment and high building water supply and drainage etc, being the best device for isolating or regulating flow in pipeline.
