Lug butterfly valve weld welding butterfly is a non-sealed butterfly valve is widely used in medium temperature materials, metallurgy, mining, electricity and other production process ≤300 ℃ 0.1Mpa nominal pressure on the pipeline to communicate hoist or adjust medium quality. Complete types of specifications, sales agents with major brands of synthetic rubber anti-chemical corrosion applications, butterfly valve performance can be improved on. Because synthetic rubber resistant to corrosion, erosion resistance, dimensional stability, good elasticity, easy to shape, low cost and so Tianjin Tanggu valve plant, synthetic rubber and can choose different performance depending on the application requirements, the use of labor to meet the butterfly conditions. Because of polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, easy to aging, low coefficient of friction, easy to shape, size and stability of valves, and can be filled, adding the appropriate material to improve its overall performance of the first valve plant in Tianjin get better strength, lower coefficient of friction sealing butterfly valve plant in Tianjin Tanggu, overcomes the limitations of synthetic rubber, which represented polytetrafluoroethylene polymer materials and filled with modified material in butterfly on has been widely used, so that the valve's performance has been further improved, to create a temperature and pressure range wider, reliable sealing performance, longer life butterfly. Valve plant in Tianjin, valves, valve provided by the Hong Kong Ming Ming Port Valve Co., Ltd., Dongguan. Port Valve Co., Ltd., Dongguan Ming (www.gdmgfm.com) strong, credible, butterfly and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the next port of the valve and you hand into the brilliant, for a better future!
