Butterfly Valve
Product structure
The multi-layer hard seal butterfly valve series products are newly developed by our company with long life and energy saving. Its structure adopts the three-dimensional eccentric principle design, and the valve seat adopts a hard seal compatible multi-layer structure, with exquisite processing and advanced technology. This product consists of valve body, butterfly plate, multi-layer valve seat, valve stem, transmission mechanism and other main components.
Features
Because the butterfly valve of this product adopts the three-dimensional eccentric principle design, the spatial motion trajectory of the sealing surface is idealized, and there is no friction and interference between the sealing pairs. In addition, the sealing material is properly selected, so that the sealing, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are reliably guaranteed. Its main features are as follows:
- Small opening torque, flexible and convenient, labor-saving and energy-saving;
- The three-dimensional eccentric structure makes the butterfly valve plate tighter and tighter, and its sealing performance is reliable, achieving no leakage;
- High pressure resistance, corrosion resistance, wear resistance, long service life, etc. "
