Diaphragm Valve

Australian Valve is the topmost Diaphragm Valve Manufacturer & Supplier in Australia. A diaphragm valve is a type of valve that uses a flexible diaphragm to control the flow of fluid in a pipeline. The diaphragm is typically made of rubber or similarly flexible material and is positioned between the valve body and the process fluid. When the valve is open, fluid can flow through the valve, and when the valve is closed, the diaphragm blocks the flow of fluid.

The working of a diaphragm valve is based on the movement of a flexible diaphragm that separates the process fluid from the valve body. The diaphragm is typically made of rubber or similar flexible material and is attached to an actuator, such as a manual lever, electric motor, or pneumatic cylinder.
