    3-way Type Diaphragm Valve


How to work the diaphragm valve

Its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving parts. The diaphragm valve is an elastic, disturbable diaphragm, which is connected to the compression part with bolts. The compression part is operated by the valve stem to move up and down. When the compression part rises, the diaphragm is lifted high, which creates a passage. When descending, the diaphragm presses on the valve body weir (if it is a weir valve) or the bottom of the contour (if it is a straight-through type). The diaphragm valve is suitable for switching and throttling.
