Performance of seal

The structure of the three-eccentric multi-layer metal hard seal, mostly are use the sandwich of metal steel and graphite.

One-layer of metal steel sheet, then one layer of graphite, and then one layer of metal steel gain. such a cycle, the specifications are different, the number of layers is also different

Application:

Lug type butterfly valves are widely used in: chemical, petrochemical, smelting, pharmaceutical, food and other industries, the medium includes SO2, steam, air, coal gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid , Hydrochloric acid, sulfuric acid, phosphoric acid, etc., the butterfly valve is used as a regulating and shut-off device on the pipeline.
