Imported pneumatic flange soft seal butterfly valve Imported pneumatic flange butterfly valve Robert brand

Imported pneumatic flange soft seal butterfly valve (Germany Robert brand)
Product Overview
Germany Robert imported pneumatic flange soft seal butterfly valve is composed of a quarter-stroke pneumatic piston actuator and a butterfly valve body. It adopts The three-dimensional eccentric principle design optimizes the spatial motion trajectory of the sealing surface. The sealing surfaces have no friction and interference with each other. In addition, the sealing material is properly selected, thereby improving the sealing performance, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve. Sex, etc. are reliably guaranteed. Pneumatic flange butterfly valve has small opening torque, is flexible and convenient, labor-saving and energy-saving.
Main features
, has small opening torque, is flexible and convenient, labor-saving and energy-saving
. Three-dimensional braided structure makes the butterfly plate close more and more tightly. Tight, its sealing performance is reliable, no leakage, high pressure resistance, corrosion resistance, wear resistance, long service life, etc., novel and reasonable design, unique structure, light weight, rapid opening and closing
/> , sealing materials are resistant to aging, weak corrosion, and have long service life.
