Valves are useful devices that help control, limit, and shut off flow in a system. In a garden irrigation system, you can use valves to control when different plants are watered. While valves are generally considered helpful, choosing the right valve can be frustrating. We hear from a lot of customers: “Too many varieties! Some do something like that! I don’t know what type of valve to use!”
do not worry! At PVC Fittings Online we offer all major valve variants. In this blog post, we’ll outline what makes each unique. For basic users, the most important thing to remember is that a valve can do one of two things: close or regulate. Some valves do either/both, but this is an easy way to think about what you need the valve to do. It can help you choose the correct valve. We will now cover each of the major valve categories.
Ball valve
pvc ball valve choosing the right valve The grayBall valve is a good example of a globe valve. They use spherical seats to stop or allow flow. There is a hole in the center of the ball so liquid can pass through when the handle is turned to the “on” position. When the handle is rotated 90 degrees to the “off” position, the fluid hits the solid side of the ball and stops.
The PVC ball valve in the picture has been disassembled so you can see its inner workings. This one uses a rubber O-ring to ensure a seal. Ball valves are globe valves because they are generally not designed to be partially open. They mean fully open or fully closed. Depending on the type of ball valve you buy, they may experience some pressure drop. This is because the diameter of the hole in the valve ball is usually smaller than the diameter of the pipe itself.
