In some applications, you want to prevent reverse flow through pipes. For these types of applications, true union ball check valves are perfect. But what are these valves and what exactly do they do? Keep reading for answers to both of those questions.
What is a True Union Ball Check Valve?
First we should define what "true union" means. For these valves, it means that the main part of the valve, the "ball," can be removed. This is great news for people who want to get the most out of their parts. If the main or central part of the valve is damaged it can be easily replaced without having to buy a whole new part.
Next, what exactly is a ball check valve? It is a valve with a rounded component on the inside that lets liquid pass through the pipe freely when traveling in the correct direction. But if liquid tries to pass back through the other way, the valve will close, stopping any reverse flow. Many of these valves use an actual ball, but ours have a slightly different design (as shown) that keeps the valve from moving around too much. This stops any wear or leaks caused by spinning.
What Does it Do?
Now that we know what a true union ball check valve is, what does it do? In short, it transports liquids in one direction. It is not recommended for gases, as the ball valve does not always create an airtight seal. Ball check valves are perfect for liquids and chemicals, however, since those don't require a completely air-tight seal.
These valves are inexpensive and easy to install, making them a great choice for anyone on a budget. A problem with them, however, lies in the fact that the ball inside can easily wear down with use. But since the true union design allows for easy replacement, any inconvenience is minimized. Also, with our line of true union ball check valves, movement of the valve itself is limited, which eliminates a great deal of the motion that causes wear and tear.
How to Take Apart a True Union Ball Check Valve
You may need to take apart one of these valves to replace a part on the inside that's damaged or not working properly. Taking apart a true union ball check valve is simple:
1. Unscrew the ends from the body of the valve and set them aside.
2. Remove the rubber seal and plastic ring.
3. Remove the ball valve piece from inside the body.
Now the valve is entirely dismantled. You can replace any of the pieces as needed. Since they aren't expensive in the first place, we recommend buying two complete valves and using the second as a source of spare parts for the one that's being used. So far, however, our customers haven't reported any failing valves or broken parts, which speaks to the quality of the product.
