Product introduction

Sd341x telescopic flange butterfly valve and pipeline expander are integrated, which can not only play the role of throttling, but also solve the elimination of internal force caused by temperature difference, that is, play the role of expansion. This valve has novel design, unique structure, small volume and light weight. The operation is light and labor-saving, the opening and closing is rapid, the sealing parts can be adjusted and replaced, the sealing performance is reliable, the flow resistance is small, the energy is saved, the applicable temperature is ≤ 80 ℃, the electric power, water supply and drainage, etc. are used as the flow regulation and closure medium, and have the function of compensating the thermal expansion and cold contraction of the pipeline.
