What is a weir type diaphragm valve and its types
As a manufacturer of weir diaphragm valve , I hope this article will help you by explaining the definition and types of diaphragm valves. What are Diaphragm Valves? Diaphragm valves utilize a flexible diaphragm to obstruct, control, or isolate the flow of fluids. The diaphragm acts as the flow control element that flexes up or down to increase or decrease the fluid flow rate, respectively. The sealing action of the valve is created as the diaphragm is pressed onto the solid dam inside the valve body. Diaphragm valves are classified as linear motion valves, which require linear motion of the flow control element. Diaphragm valves can handle liquids, gaseous fluids, and semi-solid media such as slurries, colloids, sludges, and brackish water well. These valves are ideal for handling liquids with solid particulate matter. Compared to other valves, they have a much simpler construction. Due to the minimal contact made by their internal components, the build-up of sediments and biofilms in
