How Ball Valves Work?

how-ball-valves-work

Valves play an important role in manufacturing various kinds of items we use or come across on a day-to-day basis.

From bicycles or automobiles, jet airplanes, or the oil you use for cooking—all are results of valves in some form or another. However, there are a range of valves. Each differs in not just its shape and dimensions, but also its function and application.

In this post, we look at how ball valves work, its different types, and some reasons why it should be used.

What Are Ball Valves?

These are valves that make use of a ball to navigate the movement of substances from one seating surface to another. The function of the ball is similar to a track ball found in old computer mice.

However, the ball in the valve consists of a port, which changes alignment in response to the position of the valve. For instance, when the ball valve is set to open, the port changes the direction according to the flow of the substance. When the valve is closed, however, the port adopts a perpendicular direction and acts as a seal to block the flow of substances.

Ball valves vary in the degree to which the port can change directions. In most cases, the ball valve will adopt a 90 degree rotation. However, in other cases, a 360 degree rotation is more beneficial.

What Are The Different Types Of Ball Valves?

There are also different types of ball valves. Some of these include:

  • Floating Ball Valve
  • V Port Ball Valve
  • Trunnion Mounted Ball Valve
  • Multiport Ball Valve
  • Full Port Ball Valve

The ports are made from a number of materials and metals including titanium, CPVC, chrome, brass, bronze, and stainless steel.

Why Are Ball Valves Useful?

Since valves have considerable application for the distribution of liquids and gases, ball valves offer significant convenience of requiring low maintenance and lack of leakages.

They are also useful for utilization across a wide range of industries, markets, and applications. Some of the most common areas where ball valves are used include manufacturing, oil and gas, and chemical storage industries. Before purchasing ball valves for industrial or residential use, it is recommended to evaluate the conditions so that ball valves do not suffer from corrosion.

What is a Plug Valve?

what-is-a-plug-valve

A plug valve is a simple type of valve that allows or blocks the flow of a liquid through a pipe. The plug itself is often shaped like an upside-down ice cream cone or a cylinder. A handle on top allows the user to turn the plug valve so it rotates and stops or starts the flow of liquid. A minimum of two holes, known as ports, must exist in the plug for liquid to flow. The ports are located on opposite sides of the plug, and when the plug is turned to the open position it creates a passage for the liquid to flow through.

This arrangement of two ports is known as a 2-port valve. The pipe in which the plug valve is installed has an area for liquid to flow in and another for liquid to flow out. When the 2-port plug valve is turned on, the ports line up with the holes in the pipe and the liquid flows straight through as if the plug valve was not there. Other, more complex plug valves known as 3-way valves allow liquid to flow to a combination of different ports. One port may connect to either of the opposite two ports, or all three may connect at once.

Two major categories of vales exist: stop valves and check valves. Stop valves follow a basic design structure to turn the flow of liquid on and off, or allow partial flow. Check valves, in contrast, allow liquid to travel only one way and often do not have a handle. Plug valves fall into the stop valve category.

Other stop valve types include gate valves and ball valves. Though similar to plug valves, the shape of the parts and how they work to stop the flow of liquid typically determines the specific group they belong to. Regardless of group, stop valves typically control liquid through the use of a handle.

Operation of a plug valve is simple, making it a common valve choice. The user twists the handle and the ports are moved away from the opening in the pipe. In certain valves, a full turn is not required. Quarter-turn valves, for example, only require the user to make a short, quarter turn to stop the flow of liquid. Often, plug valves can lessen the flow without turning off completely if the user turns the valve half-closed but leaves it open wide enough for some liquid to make it through the ports.
