This valve has the advantages of quick installation, simple, reliable, light weight, flexible operation, convenient maintenance, and has good sealing performance, with the connection of the pipe and the shortcut. The valve has the installation fast, easy and not subject to restrictions on site installation, etc., to facilitate the maintenance of the pipeline and the valve, the function of vibration and shock absorption, can solve the shortcoming of lines produced by temperature difference of thermal expansion and contraction of the. This valve can be applied to water supply and drainage, fire, air conditioning, gas, petroleum, chemical, water treatment, municipal, shipbuilding and other pipeline engineering as a control fluid.
1, groove butterfly valve structure is compact, small size, light weight, flexible operation, convenient maintenance.
2, the sealing performance is reliable, is not restricted by the medium flow direction (two-way seal).
3, the large flow area, flow resistance coefficient is small, the flow capacity.
4, reasonable structure, reliable sealing, convenient operation, the butterfly plate uses the whole pack of gum, anti-aging, anti radiation, durability and other characteristics for working temperature is less than or equal to 120 DEG C water, oil, mud, natural gas pipeline as the control media flow of opening, closing and adjusting device.
