What material is used for desulfurization butterfly valves?
We know that the desulfurization butterfly valve product is a butterfly valve product that must fully meet the requirements of corrosion resistance, wear resistance, flow rate, and corresponding temperature regulations, so the selection of its material is very important. So what material is used for the desulfurization butterfly valve? Next, let's give a detailed introduction to our friends.
The valve body materials of desulfurization butterfly valves are divided into: ductile iron, cast steel, stainless steel, etc. From the perspective of production cost, usually more ductile iron is chosen. If in the north, due to various factors such as weather and temperature, the valve body material needs to be cast steel or above.
The valve seat of desulfurization butterfly valves is usually lined with rubber, and the commonly used lining material currently is EPDM (ethylene propylene diene monomer rubber).
The valve plate materials for desulfurization butterfly valves can be selected: ductile iron, 304 stainless steel, lined with EPDM rubber, 1.4529, 2507 duplex stainless steel, and other materials.
For desulfurization butterfly valves used in industrial water pipelines and circulating water pipelines, the valve plate material can be ductile iron or 304 stainless steel.
The desulfurization butterfly valve products used in lime slurry medium pipelines are usually made of 2507 and 1.4529 duplex stainless steel.
The connection methods of desulfurization butterfly valves generally include wafer type and flange connection. Small diameter desulfurization butterfly valves usually use a wafer type connection, with a diameter between DN50 and DN450. For desulfurization butterfly valves with a diameter exceeding DN500, it is recommended to use flange connection.
