If you’re in the water, chemical, pharmaceutical or oil industries (among others), you may have a number of great reasons to use ball valves.
Before we get into those reasons, let’s start with an overview of how they work so you can understand a bit more about their advantages for your business.
The benefits of ball valves
Now you have a better idea of how they work, but what are the advantages of choosing this variety of valve over another?
Ball valves are often considered superior to other kinds of valves for a few reasons. Firstly, they’re great for your bottom line: plastic ball valves in particular are highly durable and can be purchased very affordably, making them a cost-effective option for your business.
Secondly, they’re so simple to use and are known for their streamlined functioning, making them more appealing than other kinds, like butterfly or gate valves. Thirdly, they effectively maintain and regulate three things: high pressure, high volume and a high flow.
With ball valves, you enjoy a quick quarter turn for on/off operation, making them ideal for a variety of uses.
Ball valve applications
These components are excellent for shut-off operations. Typically, you’ll find them being used in air, gaseous and liquid applications, as well as in vents and drains for fluid services.
Steam services also make use of ball valves, though they’re not recommended for slurry services, as the suspended particles can settle and become trapped, causing wear to the valves.
What’s a ball valve bonnet/shell?
In the video, you saw the stem of the component, as well as the ball itself – so what’s the bonnet? It’s simply the piece that fastens to the body (or is moulded around the body) and holds the stem assembly, ball and seats in place. By adjusting the bonnet, you can compress the packing (seats), which is what provides the seal. This packing is usually made of Teflon (PTFE) or O-rings (Rubber).
What are EzeeFlow plastic ball valves?
