Manual flange stop valve

Overview:

The manual flanged stop valve moves the valve disc along the axis of the valve seat by rotating the handwheel, which is driven by the valve stem. When the disc leaves the valve seat, the valve opens and the medium can pass through. When the valve disc descends and closely adheres to the valve seat, the valve closes to prevent the medium from passing through. The sealing performance of a stop valve mainly relies on the close fit between the valve disc and the valve seat, so it has high requirements for the processing accuracy and surface quality of the sealing surface.
