Introductions

The Pneumatic Actuated Butterfly Valve is a type of throttle valve and an important device in water supply and drainage piping systems. Its closing part is a disc that rotates around the valve shaft to open and close, and it is mainly used for cutting off and throttling in the pipeline. The use of a worm gear reducer enables not only the butterfly plate to be self-locking, thus stopping the plate in any position, but also improves the valve’s operational performance.

The Pneumatic Actuated Butterfly Valve is characterized by high temperature resistance, a high applicable pressure range, a large nominal diameter of the valve, and a valve body made of carbon steel. The sealing ring of the valve plate uses a metal ring instead of a rubber one. It is manufactured by welding steel plates and is mainly used for pipelines with high-temperature media. In addition, it has a simple structure, is small in size, light in weight, and is low cost.

Installations

Installing a pneumatic actuated butterfly valve is a relatively easy process that requires a few basic steps. Firstly, note that the valve can be mounted in any orientation, which provides flexibility in the installation process. Secondly, position the actuator in any direction to further simplify the installation process. However, exercise caution when handling the valve and ensure that it is properly aligned and supported to prevent any damage to the valve or the piping system. You can use specialized tools to ensure proper alignment during installation. Additionally, perform routine maintenance on the valve to ensure optimal performance. This includes checking for leaks or damage and lubricating the valve components. By following these steps, you can ensure that your pneumatic actuated butterfly valve operates smoothly and efficiently over the long term.
