                J641H pneumatic flange globe valve adopts double-acting cylinder, using upper or lower cavity air intake to control the valve remotely, easy to operate and flexible. Cylinder medium: compressed air, nitrogen. The utility model has the advantages of simple structure, convenient manufacture and maintenance, small working stroke and short opening and closing time, and the sealing surface of the closing body (disc) and the valve seat adopts conical sealing, which has the advantages of small closing force, erosion resistance and reliable sealing. The valve seat can be replaceable, and can be combined with the sealing material of the closing part at will to meet the working conditions and extend the service life.
