Features of triple eccentric butterfly valve

The triple eccentric butterfly valve is a rotary valve. The three eccentrics are all placed on the valve plate. In the valve manufacturing process, the outer edge of the valve plate adopts a partial outer spherical structure. The outer eccentric spherical surface is polished to a roughness of Ra0.4, and the spherical surface is chrome-plated or surfacing with Stellite alloy. The hardness reaches HRC45~60. The pressure resistance of the triple eccentric butterfly valve is up to 26MPa, the temperature resistance is as low as -196℃, and the temperature is as high as 700℃, and the seal achieves zero leakage.
