Electric hard seal butterfly valve

1. Product Overview
Based on the introduction of foreign advanced technology, Toyo adopts precision elastic sealing rings and three-eccentric multi-layer metal hard sealing structures, which are widely used in metallurgy, electric power, and petrochemical industries where the medium temperature is ℃ , as well as industrial pipelines such as water supply, drainage and municipal construction, used to regulate flow and load-break fluids. The valve adopts a triple eccentric structure. The valve seat and disc sealing surfaces are made of different hardness and stainless steel. It has good corrosion resistance and long service life. This valve has a two-way sealing function and the product complies with the national/valve pressure test standards.
2. Features
This valve adopts a three-eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter as you look.
The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance no matter under low or high temperature conditions, and has the characteristics of corrosion resistance and long service life.
The sealing surface of the disc is made of cobalt-based hard alloy surfacing. The sealing surface is wear-resistant and has a long service life.
The large-size butterfly plate adopts a quilted frame structure, which has high strength, large flow area, and smooth flow. Little resistance.
This valve has a two-way sealing function. It is not restricted by the flow direction of the medium or affected by the spatial position during installation. It can be installed in any direction.
The driving device can be installed in multiple stations (rotating or), which is convenient for users to use.
