Imported pneumatic wafer type triple eccentric butterfly valve Imported triple eccentric butterfly valve Robert brand

Imported pneumatic wafer-type triple eccentric butterfly valve (Germany Robert brand)
Product Overview
German Robert imported pneumatic wafer-type triple eccentric butterfly valve is a combination of high-precision triple eccentric multi-layer metal sealing butterfly valve and pneumatic Executor composition. It adopts the three-dimensional eccentric principle design to optimize the spatial motion trajectory of the sealing surface. There is no friction or interference between the sealing surfaces. In addition, the sealing material is properly selected, thereby improving the sealing performance, corrosion resistance and high temperature resistance of the butterfly valve. and wear resistance are reliably guaranteed. Multi-layered metal sealing structure, no mechanical wear, up to zero leakage, and excellent two-way sealing function.

Product Features
, Small opening torque, flexible and convenient, labor-saving and energy-saving
, Three-dimensional braided core structure, the butterfly plate is closed tighter and tighter, and its sealing performance is reliable, achieving no leakage
, high pressure resistance, corrosion resistance, wear resistance, long service life, etc.
Applications It is used as the best device to regulate flow, cut off or connect fluids on pipelines with different media such as petroleum, chemical industry, metallurgy, electric power, food, medicine, water supply and drainage, gas transportation, etc. Using different materials, the maximum working temperature can reach ℃.
