Product Description

Shengshi Huagong's pneumatic LT lug soft seal wafer butterfly valve uses compressed air as the power source, and quickly drives the butterfly plate to rotate through the pneumatic actuator to realize the opening, closing and flow regulation functions of the valve. It has the characteristics of fast response speed and high degree of automation. The lug structure is its remarkable feature. The lugs on both sides of the valve body are provided with bolt holes. The valve can be directly installed between the pipe flanges by bolts without the need for additional flange gaskets or nuts. It is easy to install and occupies little space. At the same time, it can effectively prevent the valve from shifting under the action of pipeline pressure and ensure sealing performance.

This pneumatic LT lug soft seal wafer butterfly valve has become an important equipment in the field of industrial automation fluid control with its efficient control performance and convenient installation method.
