To pass the stem rod structure, after quenching electric butterfly valve flange, with good mechanical properties and corrosion resistance, scratch resistance. When the valve opening and closing the valve stem and not only for rotary motion for the lifting operation, the valve stem packing is not easy to destroy, reliable sealing. And disc taper pin fixed to prevent out of the extended end of the clip-on butterfly design, in order to avoid the stem and disc connected to the stem of the accident when the collapse of the fracture. Connection with flanged, wafer, welded connections and lug wafer connection. Drive in the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, enabling remote control and automation. Butterfly simple structure, small size, light weight, butterfly, and the components are relatively small, on several key components can constitute a butterfly, open, they also very convenient, just to make the switch to ninety degrees, butterfly valve control fluid is very good, you can always increase traffic or reduce the flow, the valve in fluid transport any time have a certain resistance, and resistance to the main valve from its own, such as the thickness of the valve body, and if you want to reduce the fluid The resistance can only reduce its thickness. Flange butterfly clip-on signal, Ming Hong Kong valves, butterfly valves 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.
