SENSI Triple Offset metal seal butterfly valve designs in triple offset construction.The disc seal, evenly compressed around its circumference, produces a wedging effect which flexes the seal ring and reacts like a spring.

The laminated seal or metal to metal seal makes the valve can be used for high temperature and high pressure working condition with long service life and energy saving.

The triple eccentric metal seal butterfly valve is designed as a device to shut-off or regulate the working medium flow and widely installed in industrial pipelines with corrosive medium in metallurgy, iron and steel industry, power plant, petroleum, chemical industry, heat supply, inflammable gas, municipal water supply and drainage and etc.
