Product Details

Description

The structure of rubber seat butterfly valve is characterized by deviation from center of butterfly plate and center of body at stem axis. The double eccentricity effect makes the disc rapidly disengage from the seat after the valve is opened, greatly eliminating unnecessary over-extrusion and scraping of disc and seat, reducing the opening resistance, reducing wear and improving the seat life.The sharp reduction of scraping also enables the raised face butterfly valve to use metal seat, which improves the application of butterfly valve in the field of high temperature.
