The check valve is a kind of valve that many people don’t understand, and some engineers try to avoid. However, they are actually very versatile and vital to things like plumbing systems. The experts at Flex PVC can help you to better understand the importance and how to use PVC check valves.
So, what exactly are PVC check valves? A basic check valve lets water or other liquid flow through a piping system in only one directions and keeps it from reversing in the other direction and creating back-flow. The check valve does this automatically and are rather interesting because no other valve can do this and no human intervention is needed to operate them.
Where do you find PVC check valves in the home?
It wouldn’t be hard to find some sort of check valves in your home. Head to the basement and you will find one right away if you use a sump pump, as the check valve is located in the pump’s discharge line. In fact, a check valve is in many kinds of pumps in the home and in industry.
PVC check valves could also be found in applications such as steam lines, boilers, an HVAC system, compressors, etc. That’s why Flex PVC carries all sorts of different types and sizes for all of your business and home repair needs.
What makes a check valve work?
Check valves need some kind of liquid to operate, for example, in plumbing applications, water is the liquid flowing through the piping system. As the water goes through the check valve, an internal disc closes the valve as the forward flow of the water lessens or goes in the other direction. They are very simply designed to do this vital function.
The valve seals itself internally via another disc and the back pressure of the water is what turns the valve off or on, nothing mechanical is needed. In fact, a check valve shouldn’t be chosen based merely on the size of the piping, but should be chosen based on the type of application it is to be used for.
