Flanged globe valve flanged valve schematic overview of opening and closing parts are circular valve flap, flap valve and valve seat sealing surface movement direction perpendicular to the stem valve driven mainly as fully open and fully closed, do not make adjustments and throttling. Usually only one sealing surface clapper. Valves and valve seat sealing surface under the action of the valve stem sealing force to achieve valve closure. www.yyfm168.com flanged valve shut-off valve open 1/4 of the height of large diameter, can achieve full bore flow. Thus on and off time is short, the sealing surface wear. Valves, valve seat is easier to maintain, and no need to remove the entire valve from the pipeline. Disadvantage compared with other valves; media through such a valve the flow of the medium changes, thus closing the valve flow resistance in the other valves, turn off torque. The valve flange valve stem with a straight line with the lifting movement. www.yyfm168.com flanged globe valve is adaptability, one of the most versatile valve. According to their different body materials can be used for high temperature, low temperature, high pressure and corrosive media, such as toxic. Has a sealing surface, simple shape, structure length is short, fast switching speed, good manufacturing processes of the features. Widely used in electric power, metallurgy, chemical, petrochemical etc. industries. Flanged valve drive way are: manual, electric and so on. Electric can achieve remote control or automatic control of the central computer room. Open the valve to clockwise handwheel off handwheel counterclockwise. In the medium line, the cutoff valve for cutting role that the fully open or fully closed. www.yyfm168.com
