There are very few diaphragm valve parts. The primary component is an elastomeric diaphragm, which is similar to a pinch valve that uses an elastomeric liner. Shut-off in a diaphragm valve results when the diaphragm pushes into the bottom surface of the valve body. However, diaphragm valves feature precise control for regulating flow and pressure drop at various levels.
You will find two basic types of valve designs from a diaphragm valve supplier. Firstly, the weir form is well suited for general purposes, and for applications involving corrosive substances. The straight-through form is good for systems where flow direction reverses, and also for applications involving viscous fluids. These valves seldom clog.
These are some of the important characteristics of diaphragm valves:
1. Diaphragm valves are very clean, ideal for drinking water, pharmaceutical and food applications.
2. Diaphragm valves don't require much maintenance, and it's possible to replace them without dismantling pipe lines.
3. Diaphragm valves have relatively low temperature tolerances(-60 to 450 degrees F) and pressure tolerances (about 300 psi).
Find quality diaphragm valve manufacturers and diaphragm valve distributors
Other types of valves are more widely produced, but there are still plenty of diaphragm valve suppliers. Don't settle for a product that's over-priced or not quite the right fit for the application. A good diaphragm valve supplier has a wide selection, or specializes on a particular application.
Get clear information about the diaphragm valves you want to purchase
Since there are multiple styles of diaphragm valves, you may want to look at sources that provide a lot of information along with their products. This will help you make good decisions as you buy diaphragm valves.
Repair or replace your diaphragm valve part
Diaphragm valves seldom leak and they are fairly easy to replace. However, just like any valve, you should pay attention to them. Failing to maintain or replace any valve can result in untimely production shutdowns and other inconveniences.
- Diaphragm valves are not good for multi-turn operations.
