Ball valves are the choice on/off valves

Industrial settings require a number of instruments to function together in order to achieve a set target. Such

equipment has various components, carefully selected to ensure optimum function.

When it comes to selecting one or more valves for instrumentation, the choices may overwhelm you. Valves are usually designed for particular uses, most commonly being the on and off application.

Each valve is essentially different from the other, created with a specific style, size and material. Before you choose the valve, ask yourself what you need it for.

If it’s an on-off valve, we have a very good suggestion—Ball Valves!

The ideal on-off valve

On-off control valves are the most basic and therefore, frequently used valves in most industries. These valves function to start and shut off fluid flow, thereby regulating the system.

Ball valves are the most common valves used for this purpose. Others include gate, diaphragm and bellows valves.

Ball valves—function and types

These valves are designed for controlling fluid flow. A quarter turn actuation helps start or stop the fluid flow

by positioning a metallic ball that blocks the straight flow path.

This metallic ball has a large hole in its center. There are two different arrangements that can be attained by the ball to control flow.

In order to allow fluid to flow, the ball is positioned in a way that the hole is aligned with the flow path. In contrast, if it is turned in a perpendicular manner with respect to the path of flow.

This simple mechanism allows for quick shut on and off, making ball valves an ideal choice for quick, high capacity flow control.

Furthermore, the position of the handle present as part of the design is an indication of its arrangement. It can indicate if the valve is on or off. This offers higher security with sensitive applications.

Ball valves are also easy to lock out and tag for multiple reasons. These are practical and economical for almost every industry which needs a shut-on and off valve. These come in different sizes, mostly ranging from ¼ to 2 inches.

Where to buy them from?

Ideally, you should opt for a valve and pipe fitting supplier which deals with a comprehensive range of products. For instance, SealExcel offers various flow control regulators, including ball and needle valves.

The company supplies various models of standard ball valves as well as especially designed high pressure valves and two/ three way ball valves.
