Butterfly butterfly plate installed on the pipe diameter direction. Butterfly simple structure, small size and light weight. Only by a few parts. And just rotate 90 ° to quickly open and close, easy to operate, while the fluid control valve has good features. Butterfly valve in the fully open position, the disc thickness is only resistance medium flows through the valve when the pressure generated by the valve drop is small, it has a better flow control characteristics. Typically, in the throttle, adjusting the control valve and mud medium insulation, high temperature and pressure requirements of the short length of the structure station gate, opening and closing speed (1/4 turn). Low cutoff (pressure difference) forged steel gate valve, butterfly valve recommended use. In the double-digit adjusted necking ground-channel, low noise, there is the phenomenon of cavitation and gasification, a small amount of leakage to the atmosphere, when the abrasive media has, you can use butterfly. Under special working conditions throttle valve or seal stringent requirements, or badly worn, low temperature (cryogenic) under working conditions, such as when using the butterfly, the need to use a specially designed metal sealing tape adjustment device to three eccentric or double eccentric special butterfly. Forged steel gate valve flange _ _ out of Hong Kong, Guangzhou valve valve provided by the Hong Kong Science and Technology Co., Ltd., Dongguan Ming. 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.
