D371H Multi level three eccentric clamp type hard sealed butterfly valveDetailed product description：

D371H multi-level three eccentric clamp type hard sealed butterfly valve series products are long-life and energy-saving butterfly valves. Its structure is designed using the three-dimensional core principle, and the valve seat adopts a multi-level structure compatible with hard and soft seals, with exquisite processing and advanced technology. This product consists of main components such as valve body, butterfly plate, multi-level valve seat, valve stem, and transmission mechanism. Therefore, it is widely used in pipelines for corrosive media such as metallurgy, electricity, petroleum, chemical, air, gas, combustible gases, and water supply and drainage.

Characteristics of D371H Multi level Three Eccentric Double Clamp Hard Seal Butterfly Valve
Due to the three-dimensional eccentric principle design used in this butterfly valve product, the spatial motion trajectory of the sealing surface is idealized, and there is no friction or interference between the sealing surfaces. In addition, the appropriate selection of sealing materials ensures reliable sealing, corrosion resistance, high temperature resistance, and wear resistance of the butterfly valve. Its main characteristics are as follows:
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.
