Disc driven by the stem, if rotated 90 ° high temperature high pressure power station gate, will be able to complete a hoist. Change disc deflection angle, you can control the flow of media. Use conditions and the media: the butterfly valve is suitable for furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical metallurgy and power generation and environmental protection, water supply and drainage systems and other projects to transport all kinds of corrosive, non-corrosive fluids the pipe medium, for adjusting and cutting off the flow medium. Typically valve, throttle, adjusting the control and mud medium threaded forged steel valve, requiring a short length of the structure, opening and closing speed (1/4 turn). Low cutoff (pressure difference) RVCX elastic seat seal 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. Throttle in special working conditions, or require strict sealing, 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 dedicated butterfly. High pressure flat gate | Ming Port Valve | gate valve provided by the Hong Kong Science and Technology Co., Ltd., Dongguan Ming. Port Valve Co., Ltd., Dongguan Ming (www.gdmgfm.com) is Dongguan, butterfly leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the next port of the valve leading the staff warmly welcome all inquiries negotiations to create the next port of the valve a better future.
