Exhaust gas butterfly valve
Brand：Yibiao 型号：FQDF-1
The exhaust gas butterfly valve is a key valve specifically designed for industrial exhaust gas treatment systems, which can be divided into two types based on application scenarios: high-temperature exhaust gas butterfly valves and dust removal flue gas butterfly valves.
1、 Product classification and technical characteristics
High temperature exhaust gas butterfly valve
Temperature resistance range: 650 ℃~1150 ℃, mostly using carbon steel or stainless steel valve bodies, with a hard sealing structure to ensure high temperature and zero leakage.
Pressure balance design: Shanghai CSSC Mitsui's patented technology utilizes pressure differential sensors and pressure balance valves to prevent damage to butterfly valves due to excessive pressure differential on both sides.
Dust removal flue gas butterfly valve
Structural advantage: The single butterfly plate design converts axial force into sealing force through the double oblique wedge surface of the valve stem, with a leakage rate of ≤ 1%, suitable for dust and smoke media.
Material and process: The valve body and sealing surface are welded with corrosion-resistant alloy, with a working temperature of -30 ℃~425 ℃.
2、 Mainstream models in the market
Type represents model, price range, applicable scenarios
