SD41X stretch type turbine driven flange butterfly valve applications
Stretch Type Turbine Driven Flange Butterfly Valve can stretch or shrink along with the shaft within a certain range and also overcome the displacement due to non-concentricity in the pipeline’s butt-connection to the shaft within a certain range of angle, making great convenience for the installation and remove of both valve and pipeline. Suitable for the purifying pipeline in petroleum, electric power, food, beverage, medicine industries etc. and the pipeline in industrial environmental protection, water treatment, high buildings, water supply and drainage etc. to act as open-close, getting through and adjusting the medium’s flow.
