Product description

Desulfurization butterfly valve

Desulfurization butterfly valve is a valve with disc type opening and closing units to open, close and adjust the fluid channel by a reciprocating rotating 90 degrees, desulphurization butterfly valve not only has simple structure, small volume, light weight, small material consumption, also has small installation size.

Desulfurization butterfly valves must satisfy several requirements like corrosion, wear and tear, velocity, temperature and so on. All kinds of fossil fuels are sulfur-containing. Especially coal, after combustion generates a large amount of SO2, produces serious air pollution. To control pollution, flue gas desulfurization is the most efficient way. Including China, the worldly most widely used way is the lime (limestone) - gypsum wet desulphurization technology. In this process system, a variety of corrosive medium, and particle material, generate strong corrosion and wear and tear on equipment. So as to the structure and material of the valve forms have special requirements. The body uses nodular cast iron, stable and reliable, out of shape not easily; Valve plate adopts duplex stainless steel or plastic bags, coating PTFE; Stem all uses stainless steel, connection with valve plate adopts open shaft or half shaft structure without pin, so it has strong corrosion resistance.

 advantages

1, open and close conveniently, rapidly, and energy saving, small fluid resistance, can often operate.

2, with simple structure, small volume, light weight.

3, can transport the mud, and the apertures accumulate least liquid.

4, in low pressure, can achieve good sealing.

5, has good regulation performance.
