Industrial wastewater treatment valve material selection

This article analyzes the key points in the selection of valve materials for industrial wastewater treatment, emphasizing that wastewater contains corrosive components, chemicals and solid impurities on the valve performance of the stringent requirements. Core materials include: stainless steel (strong corrosion resistance, good mechanical properties, suitable for acidic and alkaline wastewater, such as butterfly valves / gate valves); fluorine plastic (such as fluorine lined valves, excellent corrosion resistance and lightweight economy, suitable for complex wastewater environment). Selection needs to synthesize the wastewater composition, working conditions and economy, to ensure the efficient and stable operation of the system, to help environmental protection goals.
