The butterfly as a piping system used to implement off and flow control components have been in many fields of petroleum, chemical, metallurgy, water, electricity and very widely used. Pneumatic valve has been known techniques valve seal forms enclosed structure, sealing material for rubber, PTFE and so on. Due to restrictions structural characteristics, suitable for high temperature, high pressure and corrosion resistance, abrasion resistance and other industries. Butterfly valve when fully opened, with a smaller flow resistance. When turned on between about 15 ° ~ 70 °, but also for sensitive flow control valves, which regulate the field in the first large-diameter Tanggu valve plant, butterfly application is very common. Since the motion of the butterfly valve disc with a rubbing resistance, so most of the butterfly valve can be used for media with suspended solid particles. Based on the strength of the seal, may also be used for powder and granular media. Valve Manufacturing, Jieyang valve, the valve is provided by the Hong Kong Ming Ming Port Valve Co., Ltd., Dongguan.
