Features:
Metal seated butterfly valve adopts triple eccentric sealing structure, there is almost no abrasion between the seat and the disc.
The sealing ring is made of stainless steel, which has double advantages of metal sealing and resilient sealing. It has excellent sealing performance both in the working condition of low temperature and high temperature, and it has features of erosion resistance, long service life.
The surface of disc is built-up welded with cobalt-based hard alloy, with which the surface is abrasion resistance, so that the service life could be long.
Metal seated butterfly valve has the function of bi-direction sealing, so that there is no limitation of flow direction when installing, also freely in terms of space and position. The valve could be installed in any direction.
