brief introduction

This valve integrates two functions of flange butterfly valve and pipeline expansion device. It can not only cut off the flow, but also eliminate the internal force caused by temperature difference. The valve can be used for regulating and intercepting the flow in electric power, urban heating, water and electricity papermaking, textile, medicine, food, water supply and drainage. It can be installed at any position without the influence of medium and flow direction. It can be used to adjust the distance between two flanges during valve installation.
