Mark Valve Technology Wenzhou Co., LtdcompanyGYR71700 high-performance soft seal butterfly valve picture:
The R-71700 series high-performance butterfly valve adopts a double eccentric structure design. The double deviation of the axis center from the center of the valve body structure, combined with the design of the valve plate circular arc sealing surface, enables the valve plate to quickly detach from the sealing seat when opened to reduce the friction of the sealing surface, and the valve plate has better sealing performance when closed. The design of the center self positioning sealing valve seat structure combined with the independent valve seat compensation seal effectively compensates for the wear of the valve seat, while reducing the friction force during sealing and greatly reducing the operating force of the valve, effectively improving the control accuracy of the butterfly valve. This series of butterfly valves has a long sealing life and excellent sealing performance, suitable for regulating and cutting off dry, corrosive gas and liquid media.
