Triple eccentric flanged butterfly valve hard seal WCB material

The flanged three eccentric butterfly valve adopts full flanged end connection for solid pipeline assembly. Uniform bolt distribution ensures stable pressure bearing and excellent tightness under high temperature and high pressure. Its triple-offset metal hard seal realizes friction-free operation and bidirectional bubble-tight shutoff with great resistance to abrasion and erosion. Available in WCB, 304 and 316, it is extensively used as main pipeline cut-off valve for heating steam, power plant piping, petrochemical oil, metallurgical hot air and desulfurization flue gas systems.

1.Rigid Flanged Connection

This butterfly type valve is integrated full-flange design ensures uniform stress distribution, high pressure resistance and excellent vibration stability for main pipeline installation.

2.Friction-free Triple Eccentric Sealing

No contact and no wear during opening and closing. Metal hard seal provides reliable bidirectional zero leakage with self-tightening sealing performance.

3.Heavy-duty Performance

The WCB eccentric butterfly valve with excellent resistance to high temperature, high pressure, abrasion and particle erosion, suitable for harsh industrial media.

4.Easy Maintenance

Flanged structure allows convenient disassembly and replacement without cutting pipes, greatly reducing maintenance difficulty.

Standard export wooden case packaging

The metal to metal flanged butterfly valve is widely used in power, petrochemical, metallurgy, central heating, water treatment, coal chemical and ship industries for steam, flue gas, hot oil, corrosive liquid and gas pipelines.
