Product Overview

The structure of the three eccentric multi-level hard sealed butterfly valve adopts the three-dimensional core principle design, and the valve seat adopts a multi-level structure compatible with hard and soft seals. It is composed of main components such as valve body, butterfly plate, multi-level valve seat, valve stem, and transmission mechanism, with exquisite processing and advanced technology. Widely used in pipelines for corrosive media such as metallurgy, electricity, petroleum, chemical, air, gas, combustible gases, and water supply and drainage

Structural Features

The product features of the three eccentric multi-level hard sealed butterfly valve are designed using the three-dimensional eccentric principle, which idealizes the spatial motion trajectory of the sealing surface. The sealing surfaces have no friction or interference with each other, and the sealing material is selected appropriately, thus ensuring the reliable sealing, corrosion resistance, high temperature resistance, and wear resistance of the butterfly valve. Main features: 1. Small opening torque, flexible and convenient, labor-saving and energy-saving. 2. The three-dimensional core structure makes the butterfly plate tighter as it is closed, and its sealing performance is reliable, achieving no leakage. 3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
