Diaphragm Valves differ from other common valves because they don’t use a valve disc. Instead, it uses a diaphragm to open and close in a linear motion to regulate and stop fluid flow. The diaphragm is connected to a compressor with a stud attached to it. The compressor moves up and down via a valve stem, so when the compressor is raised the diaphragm will lift.
Hard to spell but easy to construct, Diaphragm Valves have an actuator that is in contact with the inner membrane – or diaphragm – of the valve when it is in the open position, letting fluid flow streamlined. When closed, the diaphragm is tightly sealed against the seat in the body when it is forced downward. Compared to other conventional valves, diaphragm valves require a lot less maintenance.
Great features of Diaphragm Valves include:
There are two main types of Diaphragm Valves – Weir Diaphragm Valves and Straight Through Diaphragm Valves.
A weir design in the flow passage is designed to reduce flexing of the diaphragm component yet will still provide a smooth flow of passage for the media. Hand wheels carry a shroud that covers the stem threads at the same time as sliding over a lift indicator sleeve. The shroud protects the external stem thread from outside forces such as dust and corrosive materials.
Straight Through Diaphragm Valves are linear motion valves and bi-directional, with their main purpose of stopping the flow of the service fluid when necessary. They provide leak-proof control of abrasive and corrosive media.

Diaphragm Valves are used in applications where liquids may be corrosive at low temperatures and high-pressure situations. They are suitable for chemicals, low-velocity slurries, water, air and sludge; as well as able to be installed close to pumps and bends in vertically integrated pipelines.
