Introduction
Product use
It is widely used for water supply and drainage in water plants, power plants, steel plants, paper making, chemical industry, catering and other systems for regulation and cut-off.
Product features
·The valve adopts a medium linear structure, and its sealing performance is reliable to achieve two-way sealing and zero leakage.
·With two-way sealing function, the installation is not controlled by the flow direction of the media, nor affected by the spatial position, and can be installed in any direction.
·New and reasonable design, unique structure, light weight, quick opening and closing. Small operating torque, convenient operation, labor saving and dexterous. The sealing element can be replaced, and the sealing material has the characteristics of aging resistance, weak corrosion resistance, long service life, etc.
·The inner cavity of the valve body is covered with rubber/fluororubber, and the valve plate is made of the body material. It can also be covered with rubber/fluororubber or stainless steel for corrosion resistance.
·The overall baking paint can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is replaced.
