stainless steel turbine wafer butterfly valve
Overview
Stainless steel multi-layer three-eccentric opposing metal-seal butterfly valve series products are long-life, energy-saving butterfly valves. Its structure is designed using the three-dimensional eccentric principle. The valve seat adopts a multi-layer structure compatible with metal and soft seals. It has advanced technology. This product consists of a valve body , butterfly plate, multi-layer valve seat, valve stem, transmission mechanism and other main components, so it is widely used in pipelines with corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage.
Features: Since the butterfly valve of this product adopts the three-dimensional eccentric principle design, the spatial movement trajectory of the sealing surface is idealized. The sealing surfaces have no friction and interference with each other. In addition, the sealing material is properly selected, so that the sealing performance and durability of the butterfly valve are improved. Corrosion resistance, high temperature resistance and wear resistance are reliably guaranteed. Its main features are as follows:
1. Small opening torque, flexible and convenient, labor-saving and energy-saving.
2. The three-dimensional alloy steel core structure makes the butterfly plate close more tightly, and its sealing performance is reliable and no leakage is achieved.
3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.

1. 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.
2. 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.
3. 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.
4. The large-sized butterfly plate adopts a quilted frame structure, which has high strength, large flow area and small flow resistance.
5. 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.
6. The driving device can be installed in multiple positions (rotated 90° or 180°), making it easy for users to use.
