Flange butterfly valve

Worm gear and worm lug butterfly valves are mainly divided into metal seals and elastic seals. They belong to concentric center line butterfly valves, which reduce the torque required for switching through worm gears. Compared with handle lug butterfly valves, they are more labor-saving in the switching process during use. Gear operated lug butterfly valves consist of rubber sealed butterfly valves and ductile iron, carbon steel, or stainless steel valve plates and stems. Suitable for water supply, drainage, and gas pipelines in food, medicine, chemical, petroleum, power, textile, paper, and other industries with temperatures ranging from 80 to 120 ℃. ANSI lug butterfly valves, JIS lug butterfly valves, and EN lug butterfly valves can be customized

The application and characteristics of the worm gear switch lug butterfly valve are novel and reasonable in design, unique in structure, lightweight, and fast in opening and closing. Small operating torque, easy to operate, labor-saving, and intelligent. It can be installed in any location and is easy to maintain. The seals are replaceable, reliable in sealing performance, and can achieve bi-directional sealing with zero leakage. Sealing materials have the characteristics of aging resistance, weak corrosion resistance, and long service life. The large diameter gear operated lug butterfly valve of ASIAV series can be operated from 1 inch to 60 inches. We will make it into a large-diameter multi-stage gear operation to make valve switching easier.

Cast steel worm gear switch lug butterfly valve ASIAV series worm gear lug butterfly valve can be made of materials such as ductile iron, cast steel, aluminum alloy, etc

Gear transmission lug butterfly valve ASIAV series worm gear switch lug butterfly valve can be customized into various colors and standards - such as ANSI lug butterfly valve, JIS lug butterfly valve, EN lug butterfly valve, etc

Chinese gear operated worm gear cam butterfly valve with bi-directional sealing and zero leakage. The overall design of the fully lined rubber valve seat completely isolates the valve body from the medium in the pipeline. Since the valve body is not in contact with the medium, there is no need to consider the corrosion resistance of the valve body material when the medium inside the pipeline is corrosive. Dry shaft design ensures complete isolation between the valve stem and the medium in the pipeline, without considering the corrosion resistance of the valve shaft material. Only standard valve stem materials need to be selected. Low operating torque. Lightweight, easy to install and maintain. The full bore design greatly improves the flow coefficient and meets the efficient flow of the medium inside the pipeline.
