First, the pneumatic fixed ball valve Overview
Q647 pneumatic fixed ball valve in the oil, gas, coal and ore mining, refining processing and pipeline transportation system; in chemical products, pharmaceuticals and food production species; in hydropower, thermal power and nuclear power generation system ; It is widely used in irrigation and drainage systems of agricultural fields and in irrigation and drainage systems of urban areas and industrial enterprises; and is widely used in the production system of gold control, which is closely related to production and construction, national defense construction and people's livelihood Important mechanical products. Ball valve closed in a variety of piping systems used to cut off or connect the media flow, the media in accordance with the predetermined procedure delivered to the various designated points.
