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.
- Confirm installation orientation and maintenance access against the instructions for the selected valve and piping arrangement.
- The seals can be replaced. Confirm bidirectional sealing capability, permitted differential pressure and leakage acceptance for the selected configuration against the applicable test report.
- Confirm the selected sealing material against the actual medium and operating conditions, and follow the applicable inspection and maintenance instructions.
Large Diameter Gear Operated lug butterfly
Trekre 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.

Gear Transmission Lug type Butterfly Valve
Trekre 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
- Confirm sealing capability in each pressure direction and the agreed leakage acceptance criteria for the supplied configuration.
overall design
- The fully lined rubber valve seat completely isolates the valve body from the medium in the pipeline. The lining separates the body from the process medium in the intended construction. Confirm lining compatibility, body material and external exposure for the actual service; do not waive the material review solely because the valve is lined.
- For the described dry-shaft construction, confirm the shaft material, sealing arrangement and compatibility with the actual medium and service conditions. The dry-shaft description alone does not establish a suitable shaft grade for every application.
- 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.
