Lined butterfly valve with the valve stem together with the rotation of the butterfly valve plate for opening and closing parts, to achieve the valve open, close and adjust. Butterfly valve in the pipeline in addition to cut off and closure with the outside, in recent years has been the main indicator of the evaluation of the performance of the seal, favored by the market. In addition, the butterfly still genre and small weight, product has the advantages of simple structure, compared with the same parameters valve, the average weight of 30~50%, the disc can be rotated 90 degrees to achieve the opening and closing process, because the media is approximately equal to the force, shaft on both sides of the disc by the torque on the contrary, because some smaller opening and closing torque.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
