Triple Offset PTFE Multilevel Butterfly Valve

◆ Triple eccentric multi-level hard-sealed butterfly valve series products are long-life, energy-saving butterfly valves. Its structure adopts three-dimensional core design principle, the valve seat adopts a multi-layer structure compatible with hard and soft sealing, exquisite processing and advanced technology. This product is composed of main components such as valve body, butterfly plate, multi-level valve seat, valve stem and transmission mechanism. Therefore, it is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage and other corrosive media pipelines.

◆ Because the butterfly valve of this product adopts the three-dimensional eccentric principle design, the space movement trajectory of the sealing surface is idealized, and there is no friction and interference between the sealing surfaces, and the sealing material is selected appropriately, so that the butterfly valve has a sealing performance and corrosion resistance. , High temperature resistance and wear resistance have been reliably guaranteed.

◆ The opening torque is small, flexible and convenient, labor-saving and energy-saving.

◆ The three-dimensional cored structure makes the butterfly plate tighter and tighter. Its sealing performance is reliable and leak-free.

◆ High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
