Gear Operated lug type butterfly valve is mainly divided into metal seated and Resilient seated, which belong to Concentric butterfly valve, the torque required for switching is reduced by the worm gear,Compared with the handle lug butterfly valve, it is more labor-saving during the switching process
Worm Gear Switch Lug Butterfly Valve Applications and Features
Gear Operated lug type butterfly valve is composed of rubber sealing butterfly valve and carbon steel or stainless steel valve plate and valve stem. It is suitable for water supply and drainage and gas pipelines with temperature ≤80～120℃, such as food, medicine, chemical industry, petroleum, electric power, light textile, paper making, etc. Its main features are:
- Novel and reasonable design, unique structure, light weight, quick opening and closing.
- Small operating torque, convenient operation, labor-saving and smart.
- It can be installed in any position and easy to maintain.
- The seals can be replaced, and the sealing performance is reliable and can achieve zero leakage of bidirectional sealing.
- The sealing material has the characteristics of aging resistance, weak corrosion resistance and long service life.
Large Diameter Gear Operated lug butterfly
ASIAV series Gear Operated lug type butterfly valve can be made from 1 inch to 60 inches, and we will make it into Multi-level Gear Operated for large diameters, which makes the valve switch easier.
cast steel Worm Gear Switch Lug Butterfly Valve
ASIAV series Worm Gear Lug type Butterfly Valve can be made of ductile iron, cast steel, aluminum alloy and other materials
Gear Transmission Lug type Butterfly Valve
ASIAV series Worm Gear Switch Lug type Butterfly Valve can be customized into various colors and various standards-such as ANSI lug type butterfly valve, JIS lug type butterfly valve, EN lug type butterfly valve, etc.
China Gear Operated lug type butterfly factory
- Two-way sealing, zero leakage.
overall design
- The fully lined rubber valve seat completely isolates the valve body from the medium in the pipeline. Since the valve body does not contact the medium, the corrosion resistance of the valve body material does not need to be considered when the medium in the pipe is corrosive.
- Dry shaft design, the valve stem is completely isolated from the medium in the pipe, no need to consider the corrosion resistance of the valve shaft material, just choose the standard valve stem material.
- Low operating torque.
- Light weight, easy to install and maintain.
- The full diameter design greatly improves the flow coefficient to meet the efficient flow of the medium in the pipe.
