Set the tone for a confident and authoritative discussion

At first glance, diaphragm valves may be intimidating due to their complex construction and functionality. However, with a better understanding of the technology, it is possible to confidently select the right type of valve for any application. This guide provides a comprehensive overview of all things related to diaphragm valves so that you can make an informed decision when the time comes.

II. What is a Diaphragm Valve?

Define diaphragm valves and their key components

Diaphragm valves consist of a valve body, diaphragm, and actuator. The valve body is the core part of the entire structure and contains an opening that can be closed or opened with the help of the diaphragm. The diaphragm itself is typically made from rubber or plastic and is connected to the actuator, which is responsible for moving the diaphragm to open or close the valve.

Explain how diaphragm valves work

The diaphragm valve works by using a controlled pressure differential between two sides of the diaphragm. This pressure differential is created when an external force, such as a manual lever or electric motor, moves the actuator. This causes the diaphragm to flex, opening or closing the valve depending on the direction of movement.
