Product Overview: 

LXHQ-HG double eccentric high performance butterfly valve is a high performance sealing butterfly valve with double eccentric structure design. The valve plate can be quickly separated from the sealing ring in the opening process, so that the abrasion is reduced, the sealing service life is prolonged, and the valve plate is widely suitable for fluid control under high temperature, high pressure, strong corrosion and severe working conditions. The double eccentric structure overcomes the shortcomings of fast wear and large opening and closing torque of the traditional central line butterfly valve sealing pair, and has more excellent opening and closing flexibility and long-term sealing performance. This series of butterfly valves are widely used in petroleum, chemical industry, electric power, metallurgy, papermaking, pharmacy, shipbuilding, food and other industries, suitable for the regulation and cut-off of steam, oil, gas, corrosive medium, slurry and other media.
