Membrane valve EC011426
A membrane valve is a valve in which the flow is controlled by a flexible diaphragm (membrane) that is pressed against a weir or seat to shut off the flow. The diaphragm isolates the fluid from the moving parts of the valve, ensuring tight sealing and protection against contamination.
