What’s The Difference Between A Diaphragm Valve And Diaphragm Seal? Diaphragm valves and diaphragm seals are two important parts of a pneumatic system. A diaphragm valve is the part that controls or regulates the flow through a system while a diaphragm seal can be found on either side of a valve, preventing leaks when the device is not in use. Find out more about these two devices and how they differ from each other by reading this article!
What is a Diaphragm Valve? A diaphragm valve is a valve with a diaphragm as the main component that seals the valve. The diaphragm is attached to a stem that opens or closes the valve as it is moved up or down. Diaphragm valves are used in many industries, such as chemical, food and beverage, pharmaceutical, and water treatment.
There are two types of diaphragm valves: weir and straight-through. Weir diaphragm valves have a raised edge on the inside of the body that helps to seal the valve when it is in the closed position. Straight-through diaphragm valves have a flat surface on the inside of the body and do not have a raised edge.
What is a Diaphragm Seal? A diaphragm seal is a type of valve that uses a diaphragm to prevent the escape of fluids or gases. The diaphragm is a flexible membrane that is placed between two fixed surfaces. When the valve is opened, the diaphragm moves to allow the flow of fluid or gas. When the valve is closed, the diaphragm moves to block the flow.
