What is Reduced Port Ball Valve? Uses and Working

Reduced Port Ball Valve

Reduced port ball valves are essential components in many industrial applications. In this blog post, we’ll discuss what reduced port ball valves are and how they work. We’ll also discuss the various uses of reduced port ball valves so that you can decide if it’s the right fit for your application.

What is Reduced Port Ball Valve?

A reduced port ball valve is a type of valve that has a smaller opening (or “port”) than full-port or standard-port ball valves. This means that it provides less flow than other types of valves, but this also makes it more suitable for certain applications where a lower flow rate is desired.

Reduced Port Ball Valve Uses

Reduced port ball valves can be used in various ways, including controlling the pressure or flow rate of liquids, gases, or steam. They are often used in commercial and industrial applications to regulate chemical processes or to maintain precise temperatures. They can also be used in water treatment and filtration systems to control the outflow from tanks or reservoirs.

How Does It Work?

The essential operation of a reduced port ball valve is similar to that of any other type of ball valve. A metal sphere with an internal hole (the “ball”) is attached to a handle via an axle. Turning the handle rotates the axle, which rotates the sphere inside the valve body. This opens and closes the valve depending on which direction it is turned; when opened fully, the hole in the sphere aligns with two openings in the body, allowing fluid to pass through them freely; when closed completely, these two openings are blocked off by the sphere, and no fluid can pass through them. The difference between a reduced port ball valve and other types of valves lies mainly in its size—the internal hole in its sphere is smaller than those typically found on full-port or standard-port valves, limiting its flow rate accordingly.


Reduced port ball valves play an important role in many industries due to their ability to accurately control flow rates while still offering reliable performance. Due to their limited flow rate capabilities, they may not be as versatile as their full-port counterparts. Still, they can prove invaluable when precise regulation is needed for critical operations such as temperature maintenance or chemical processing.
